brute force method for reducing ADC noise -- average a ridiculous number of samples
(because, for some reason, even though 64 samples is plenty in a test program,
it ends up being extremely erratic when used inside Anduril... and I'm not sure why)
also, use 15-bit ADC values instead of 16 bits, in the temperature logic
(to help protect against integer overflows)
... but this code still doesn't work well. It regulates down *very* fast, and then
gradually rises until the next extra-fast drop-down. :(
... also, tempcheck mode sometimes changes by 4-5 C between readouts, which is worrisome.
... and factory reset is still broken.
