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.

Add link to SW page to the list of documents
The page is linked from the system description page,
    but is probably hard to find.

Receive USS and hash into CDI
- We're OK with USS not being loaded, and use an all-zero USS if so.
- We require USS to be loaded before app_size (if at all).
