Add Record and Playback

[DaPortlyJester]

For next year or in between competitions, we want to add software support for recording robot actions, and playback to support simple autonomous setup without a gyro or encoder working.

To expand on this, we would want to add a feature that can be toggled on/off, which would record all user input during the time period to a file.

The file must also be able to be 'played back' during autonomous mode.

Ideally, the logging/playback would compress the data if possible.
E.g.,
Instead of 1 entry for each control loop:

• Left and right thumbsticks at full speed forward at time 0.01
• Left and right thumbsticks at full speed forward at time 0.02
• Left and right thumbsticks at full speed forward at time 0.03
• ...
• Left and right thumbsticks at full speed forward at time 0.5

Have a condensed entry:

• Left and right thumbsticks at full speed forward for 0.5 seconds
