To sync TM and TS data after flight, store the TM tick data in the log
along with the TM state. This should provide sufficient data to
synchronize the two data streams.
Use the TM state to enable/disable logging, log from boost to landing
and otherwise do not log.

Turns out the AVR we're using sucks at doing SPI slave. To get it
running at a reasonable data rate, I had to completely gut the
'sensible' code and run everything from the ISR with interrupts
disabled.
Even with this, the maximum SPI clock rate is somewhere around
200kHz. That's due to the singled buffered nature of the transmit
queue, the amount of time available between finishing one byte and
starting the next is very very small.

Listen on the SPI slave port for commands from TeleMetrum.
Run logging during flight, based on flight state.
Return recent data for telemetry.

Initializes the Newhaven display and has a few simple commands to show
some text.

ATmega32u4 has only 2.5kB of ram, so check the output of the compiler
to make sure it will work.

Note that SLEEP mode must be disabled or extra ADC interrupts occur,
which messes up saving ADC values to the right channel.
