02/24/2024 Test Launch Version (BB Black) (#11)

* Adding a 90% completed, compilable but untested ADS

* Made basic changes to actuator & sensor. Also added motor class

* Removed unnecessary .cpp files

* Updated sensor & actuator classes, finished ads, added variable time step to kalman filter, set up all tests for future assertions

* Relocated 'main' to 'active-drag-system.cpp'. Added more info to README

* Removed main.cpp

* Added more details to README

* Changed some function parameters from pass-by-pointer to pass-by-reference. Also removed the std namespace

* Started writing the test cases

* Updated the .gitignore file

* Removed some files that should be gitignored

* Up to date with Jazz's pull request

* Test Launch Branch Created; PRU Servo Control with Test Program

* Added I2C device class and register IDs for MPL [INCOMPLETE SENSOR IMPLEMENTATION]

Needs actual data getting function implementation for both sensors and register IDs for BNO, will implement shortly.

* Partial implementation of MPL sensor

Added startup method, still needs fleshed out data getters and setters and finished I2C implementation. MOST LIKELY WILL HAVE COMPILATION ISSUES.

* *Hypothetically* complete MPL implementation

NEEDS HARDWARE TESTING

* IMU Header and init() method implementation

Needs like, all data handling still lol

* Hypothetically functional (Definitely won't compile)

* We ball?
