Remote shell (WIP)

[Elan456]

Description

Summary of Changes

• Telemetry can now take a CommandLine ptr
• Telemetry can detect the sequence "ccc" on the input and switch into command mode.
• In command mode, Telemetry will switch the given CommandLine to act upon the radio stream, creating a remote shell.
• In command mode, Telemetry stops streaming telemetry data over the stream to allow a clean stream for the CommandLine.
• Telemetry will exit command mode if the CommandLine doesn't receive any input bytes after a set timeout period
• Add CommandLine::switchUART and CommandLine::useDefaultUART
• CommandLine now tracks the timestamp of the last input it received
• Refactor SerialSim preprocessor constants into their respective simulation sensor headers.

Motivation

• The CommandLine shell is extremely useful for executing commands on MARTHA.
• Currently, the command line only works over a USB connection.
• With this, we can re-purpose the radio connection for command execution using our existing command line system.
• We can also use this to do a full fidelity data dump over the radio.
