Sleep/GPS

GPS Sleep and timing not accurate. The GPS sleep does not enter a high level of sleep, using a whopping 240 uA of power while "asleep".

MCU sleep has not been worked on yet

Being worked on.

Solved!
GPS Sleep Problems were fixed by, well, not much. I realized that the FTDI adapter I was using used 20 ma, so it was actually only pulling 4 ma. When using software backup mode and PSMCT, I can get it even lower.

MCU Sleep was done with the Arduino Low Power Library from library manager let me put the MCU into deep sleep between transmissions.
