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.
