Implement vertical device movement measurement

[voidlord]

Implement functions required to measure vertical movement of the device.

Implementation should use values provided by SensorAPI (https://developer.android.com/guide/topics/sensors/sensors_motion), and should return movement relative to Earth, instead of local.

Transformation formula needs to be researched.

Research has concluded with two types of formulas to get the movement:

• https://stackoverflow.com/a/14988559 (Needs further testing on accuracy)
• https://stackoverflow.com/a/36477630 (During prototype testing, ran into issues with .MultiplyMV() causing fatal errors)

Currently paused, waiting for https://github.com/Just-Pong/just-pong-android/issues/5 to solve

https://github.com/Just-Pong/just-pong-android/issues/5 is partially concluded and should not hold back this ticket anymore.

https://github.com/Just-Pong/just-pong-android/issues/1#issuecomment-1296201778 Further testing using a virtual device proved, that the first formula should be accurate enough.

This algorithm only detects movements, and doesn't convert data to Earth coordinates.
