refactored how interrupts work...
set a flag and return immediately,
then handle the actual logic later during a less-critical code path
Enables smarter responses to standby wakeups.
Seems to fix missed button presses during standby,
and most of the too-fast sleep ticks.
Also eliminated waits from button state measurement, so it can happen easier during standby.
(also eliminates the chance of an infinite loop on extra-noisy hardware)
Also might improve timing-sensitive interrupts like attiny85 PWM channel 4,
or a PWM-DSM hybrid technique I'd like to try.
BUT this change also appears to break the thermal sensor, so that needs to be fixed.
