Added utility methods + naming scheme changes

[Daniel1464]

1. Changed "getGamePiecesByType" to "getGamePiecePoses" which makes it a bit more descriptive
2. Added "getNotePoses" method to make mispelling the gamepiece type less common for notes(in 2025, we can add the respective methods for the new gamepieces)
3. Renamed "GamePieceOnFieldSimulation" to "GamePieceOnField" to make it more consistent with "GamePieceProjectile"
4. Change the return types of getGamePiecePoses/getNotePoses to arrays instead of lists to allow for easier logging(most logging frameworks unfortunately don't support list logging)
5. Updated the docs as well(currently, the docs demonstrate logging a List via Logger.recordOutput which doesn't work).

Note: I'm not sure if there's anything I have to do in order to update the javadocs(they seem to be autogenerated, but idk how to refresh them)

Also, after realizing that fps' changes haven't been merged yet, this should probably hold off to another time(unless if beta 2 comes out with his changes)

LGTM, and thanks for the help!

But you're right, I should probably merge this after merging the new APIs by @oh-yes-0-fps, otherwise there'll be a ton of conflicts.
