This milestone will be met by the following:

• Decide on command structure to the MCU (#97)
• Decide on structure of output from the MCU for the PC to parse
• Implement parsing/serialization of the command/output structures on MCU and PC side
• Unify command and output format between MCU and PC (one source of truth)
• Implement sugar for writing a human-readable command and mapping it to the bytes sent to the MCU. This would allow for writing test scripts with a shell-like format (e.g. soccerbot-cmd get --forced imu motor) to be used in CI runtime tests. Similarly, sugar for MCU output would make tests more readable when checking for expected output.
