Where to begin…. (#13)

+/- Reworked collection of altimeter related functions into altimeter class
+/- Reworked bno055 class to be imu class with minimal functionality

\- Removed external Kalman filter implementations in favor of own in house version
\- Removed any/unused files
\+ Added buffer logger for when sitting on pad for extended period of time in effort to prevent filling of flash chip
\+ Added heartbeat LED for alive status
