-Now uses Drivers/lib/mqtt_client.py MQTT client code instead of own.

-Rewrote most code to use event listening for button presses instead of looping & sleeping

-Moved button code into own driver folder: button_control

-Created new MQTT topic - bike/{ID}/button - for button communication.

-Now uses parsed arguments from script with defaulting to environment variables rather than hardcoded values.

-Changed to use report sub-topic instead of control sub-topic as the buttons only "sense"

- turns out there was a much cleaner way to import the mqtt_client from lib.

- Moved old research into archive folder.

- Moved old drivers that were no longer relevant to archive folder.

- Moved unused Unity project in IoT repo (believe this may be the old game which is no longer being developed) to archive folder.

- Moved remote connect code, due to breaking and being undocumented, to archive folder.

- Moved workout drivers into own sub folder in Drivers folder since a lot of them are no longer relevant but we may want to take inspiration from them for the mobile app.

**This looks super scary but everything is being preserved and just dumped into the archive folder for later exploration or use if needed.** The repo is currently very cluttered with redundant and abandoned projects and research. This makes it very difficult to discover relevant code when combined with the lack of documentation.
