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.

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

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.

Leave these disabled while processing stuff; otherwise we receive a
steady stream of them.

We leave USB data lying around until called for, which results in
constant badgering if interrupts are enabled. Disable them until there
isn't any data left.

As usual, the key is to know when to send 0-length IN and OUT
packets. Needs a bunch of cleanup, but it's working now.

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.
