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.

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

We've got ram for it at this point, and it's nice to have more data
from before boost detect.

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

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

Setting the stack pointer takes two instructions, so make sure we
don't get an interrupt in the middle of it. Let the restoration of
SREG set the interrupt flag as appropriate.

Some packets are flowing, although it's not working right.
