fw: Introduce an explicit state machine - changes protocol!
...
We introduce an explicit state machine (see README).
With the new states we:
- combine setting size and USS to a single command.
- start the device app immediatiely when having receceived the last
data chunk and returning the digest.
- Loop forever and wait for the stick to be removed if we end up in
unknown state.

Clear all RAM during start
...
Since SRAM has some data remanence even without power it seems good
hygien to clear all RAM when starting the device so as not to leak
potential sensitive data between device apps.

Use the new firmware-only RAM for CDI computation
...
To protect UDS we use a special firmware-only RAM for both the in
parameter to the blake2s() function and for the blake2s_ctx.

Pass the blake2s_ctx to blake2s() as arg
...
Instead of allocating the blake2s_ctx in the blake2s() function we
pass it as a pointer as an argument to be able to better control where
the variable is in memory.

Adjust and document the firmware state-machine, including USS
...
In particular, order of LOAD_USS and LOAD_APP_SIZE is not required, but
the need to send both is documented. This is followed up with adjustment
in the host programs' Go code, to try to reinforce this. LoadApp() will
take the secretPhrase parameter (to be hashed as USS), and loadUSS()
will be unexported.
Correct CMD/RSP lengths in pseudo-code.

- We're OK with USS not being loaded, and use an all-zero USS if so.
