Harmonize firmware description
...
The links to firmware.md disappeared earlier so this change
incorporates some of the the text there in under the Firmware heading
in software.md. Also changes the names of the commands in the state
machine to the same names as in the rest of software.md.
Mention the Zmmul extension and what it means and possible workarounds
for people developing with clang < version 15.

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.

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.
