Upgrade bitcoin and bdk to latest version
The latest version allows us to access `miniscript` via `bdk` which
removes the need for declaring it as an extra dependency.

swap_setup instead of spot_price and execution_setup
Having `spot_price` and `execution_setup` as separate protocols did not bring any advantages, but was problematic because we had to ensure that `execution_setup` would be triggered after `spot_price`. Because of this dependency it is better to combine the protocols into one.

Combining the protocols also allows a refactoring to get rid of the `libp2p-async-await` dependency.

Alice always listens for the `swap_setup` protocol. When Bob opens a substream on that protocol the spot price is communicated, and then all execution setup messages (swap-id and signature exchange).

Make it easier to create a bitcoin::Wallet for testing
Forcing the user to create an implementation of `EstimateFeeRate`
every time they want to create a wallet for testing is tedious and
leads to duplicated code.

The implementation for tests is rarely dynamic and thus can be
simplified to static arguments.

This also allows us to provide convenience constructors to make tests
that don't care about fees less distracting by reducing the number of
constants that are floating around.

Update assert_weight test to account for a range up to 8 bytes.
Weights fluctuate because of the length of the signatures. Valid ecdsa signatures can have 68, 69, 70, 71, or 72 bytes. Since most of our transactions have 2 signatures the weight can be up to 8 bytes less than the static weight (4 bytes per signature).

Dynamically chose fee for TxRefund and TxPunish.
Alice chooses the fee for TxPunish because she is the one that cares.
Bob chooses the fee for TxRefund because he is the one that cares.

Note must be taken here because if the fee is too low (e.g. < min tx fee) then she might not be able to publish TxRedeem at all.

Alice to validate Bob's PSBT for correctness
In order for the re-construction of TxLock to be meaningful, we limit
`Message2` to the PSBT instead of the full struct. This is a breaking
change in the network layer.

The PSBT is valid if:

- It has at most two outputs (we allow a change output)
- One of the outputs pays the agreed upon amount to a shared output script

Resolves #260.

Greatly reduce load onto the Electrum backend
We achieve our optimizations in three ways:

1. Batching calls instead of making them individually.

To get access to the batch calls, we replace all our
calls to the HTTP interface with RPC calls.

2. Never directly make network calls based on function
calls on the wallet.

Instead, inquiring about the status of a script always
just returns information based on local data. With every
call, we check when we last refreshed the local data and
do so if the data is considered to be too old. This
interval is configurable.

3. Use electrum's notification feature to get updated
with the latest blockheight.

Eliminate build_bitcoin_punish_transaction
We reduce indirection by constructing TxPunish directly based off
`State3` and make the type itself more powerful by moving the logic
of completing it with a signature onto it.

Change imports_granularity to module
This reduces the overall amount of LoC that imports take up in our
codebase by almost 100.
It also makes merge-conflicts less likely because there is less
grouping together of imports that may lead to layout changes which
in turn can cause merge conflicts.

Remove traits in favor of using the wallet struct directly
Abstracting over the individual bits of functionality of the wallet
does have its place, especially if one wants to keep a separation
of an abstract protocol library that other people can use with their
own wallets.

However, at the moment, the traits only cause unnecessary friction.
We can always add such abstraction layers again once we need them.

Remove BuildTxLockPsbt and GetNetwork traits
These traits were only used once within the `TxLock` constructor.
Looking at the rest of the codebase, we don't really seem to follow
any abstractions here where the protocol shouldn't know about the
exact types that is being passed in.

As such, these types are just noise and might as well be removed in
favor of simplicity.

Upgrade to bdk 4.0
To achieve this we also:

- upgrade rust-bitcoin to 0.26
- upgrade bitcoin-harness to latest version (which also depends bitcoin 0.26)
- upgrade to latest edcsa-fun
- replace cross_curve_dleq proof with sigma_fun (to avoid an upgrade dance over there)

a0ef1f96ec Replace bitcoind wallet with bdk wallet
The bitcoind wallet required the user to run a bitcoind node. It was replaced with a bdk wallet which allows the user to connect to an electrum instance hosted remotely. An electrum and bitcoind testcontainer were created to the test the bdk wallet. The electrum container reads the blockdata from the bitcoind testcontainer through a shared volume. bitcoind-harness was removed as bitcoind initialisation code was moved into test_utils. The bdk wallet differs from the bitcoind wallet in that it needs to be manually synced with an electrum node. We synchronise the wallet once upon initialisation to prevent a potentially long running blocking task from interrupting protocol execution. The electrum HTTP API was used to get the latest block height and the transaction block height as this functionality was not present in the bdk wallet API or it required the bdk wallet to be re-synced to get an up to date value.

Upgrade tokio to 1.0
Upgrade bitcoin harness dependency to latest commit

Upgrade backoff to fix failing tests. The previous version of backoff had a broken version of the retry function. Upgraded to a newer comit which fixes this problem.

Upgrade hyper to 0.14 as the 0.13 was bringing in tokio 0.2.24

Upgraded bitcoin harness to version that uses tokio 1.0 and reqwest 0.11

Upgrade reqwest to 0.11. Reqwest 0.11 uses tokio 1.0

Upgrade libp2p to 0.34 in preparation for tokio 1.0 upgrade
