fw: Simplify logic
Switch on state, then read commands specifically in the states that
allow reading of commands, then switch on specific command.

fw: Remove state init_loading, introduce state fail
- We always assert on allowed commands in a state.
- We don't allow FW_CMD_LOAD_APP to be used twice.
- Enter fail state on read buffer overrun, header endpoint not for us,
  header parse error, and unknown firmware command.

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.
