Refactored for teensy 4.0, xEvi hardware

- Switched to platformio, ino -> cpp - MPRLS for pressure sensor - Added basic ICM support - Removed widi, battery, other features not supported in xEvi - Removed legacy options/processing - Added LED strip support - Added encoder support - Reworked menu code to use encoders/be more flexible
