    Display-shifting code overhauled- previous configuration printed certain data subsets
    regardless of whether that data was part of the incoming packet. Current version receives data,
    then once the packet has been processed runs a switch-case based on the button input to
-   determine what to print to the LCD.
+   determine what to print to the LCD. (Added several new display modes as well- flag-confirmation, sd-check)
    Also slightly modified the button code to prevent multi-incrementing for each time the button is pushed
    Added code to control several LEDs- whether the fin override is in place, whether the servo has power,
    whether communications are working, and three which indicate the fin position
