[0.1-t03_11] adding sleep library freezes the MCU

[cntlsn]

when adding the sleep library (https://github.com/opencarecc/inpe/tree/0.1-t03_10/software/utilities/Sleep_Library) to https://github.com/opencarecc/inpe/blob/0.1-t03_10/software/inpe-t03_010/inpe-t03_010.ino the system freezes when entering sys_sleep_in_callback

commenting all the functions inside sys_sleep_in_callback will still make the system freeze.
I think it has to do with VM_TIMER_ID_PRECISE used also inside https://github.com/opencarecc/inpe/blob/0.1-t03_10/software/inpe-t03_010/sensor_loop.cpp
