This lets TeleScience log these values so the log can be matched with
a suitable TeleMetrum log.

Cherry-pick from 8624213ee204bfdcb219c65b3618751d8278d9db
This will make it easier to figure out what the contents of the flash
should look like from altosui; the current 'guessing' mechanism will
not scale to many more formats.

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.

Use a pull-up on telescience and tri-state input on telemetrum at boot
time. Enable logging by pulling the TM output low and enabling as an
output, disable by pulling the TM output high and switching back to
input mode.
Also, ignore pin state changes for 5 seconds at boot to give things a
chance to settle down.
Should work when both boards are powered up together.

Probably not the best plan to call printf from an interrupt handler.

Use the SPI chip select (SS) which is hooked to port B0.

Adds list and delete commands, making them compatible with telemetrum
and telemini equivalents.
