Our libp2p version is out of date, and we need to tackle the upgrade even though it's a significant undertaking. This'll also fix some other [issues](https://github.com/UnstoppableSwap/core/issues/95).
## This PR includes the following changes:
- Breaking network protocol change: The libp2p version has been upgraded to 0.53 which includes breaking network protocol changes. ASBs and CLIs will not be able to swap if one of them is on the old version.
- ASB: Transfer proofs will be repeatedly sent until they are acknowledged by the other party. This fixes a bug where it'd seem to Bob as if the Alice never locked the Monero. Forcing the swap to be refunded.
- CLI: Encrypted signatures will be repeatedly sent until they are acknowledged by the other party
- CLI+ASB: Libp2p network errors in request-response protocols are now propagated throught the event loop channels. This allows the caller to retry if an error occurs (e.g timeout)
