TODO: Viz this, for now follow pin numbers on utilites.h

TODO List

1. figure out how to connect board to american cel network & start publishing data to desktop live via MQTT
2. push encoder data to buffer via interrupts so data isn't lost while the board is pushing buffer to SD card 2.b You could in theory use one core of the esp to read encoder and one to push to SD card
3. (optional) Draw a cute lil speedometer on the LCD screen
4. record accelerometer data
5. seperate encoder stuff into a seperate class for better code org
6. record GPS data to reconstruct bike travel path and speed at each point for sick ass diagrams
7. write a setup guide
