Share file/map with QR

[kylecorry31]

Split the file into multiple QR codes and scan one at a time (specify the sequence number in each QR)

This might not be feasible unless the file is really small - more testing needed

There might also need to be a way to automatically move to the next QR - maybe a combination of the flashlight and light sensor or screen to screen communication (both scanning QR codes - one device telling the other when to switch)
