Refactor PlaybackController

[ScribbleTAS]

Continuation of #179

Changes

PlaybackController

The main focus of this PR was to reduce complexity in the PlaybackController, the main class for starting/stopping recordings/playbacks.

Up to now, everything playback related was added to the controller, without any consideration for architecture.

Hooks into the VirtualInput-System are now added via EventVirtualKeyboardTick, EventVirtualMouseTick, EventVirtualCameraAngleTick.
Any future TASmod extensions can use these too by implementing EventVirtualKeyboardTick in your class and registering it via EventListenerRegistry.register(YourClass)

PlaybackMetadata

The first lines of the TASfile contain metadata that is used for storing playback specific configuration.
In Alpha9 this metadata consisted of:

• Author of the TAS
• Title of the TAS
• Playtime / Runtime of the TAS
• Rerecords
• Starting location of the TAS
• Starting seed of the TAS

All of these (except starting seed, which is due in #190) have now been rewritten in the form of PlaybackMetadata.

public class CustomMetadataExtension implements PlaybackMetadataExtension {
	@Override
	public String getExtensionName() {
		return "Name";
	}

	@Override
	public void onCreate() {
		// Unused atm
	}

	@Override
	public PlaybackMetadata onStore() {
		PlaybackMetadata metadata = new PlaybackMetadata(this);
		metadata.setValue("Test", "Test")
		return metadata;
	}

	@Override
	public void onLoad(PlaybackMetadata metadata) {
		System.out.printLn(metadata.getValue("Test"));
	}

	@Override
	public void onClear() {
		// E.g. When /clearinputs is run
	}
}

After registering this class under PlaybackMetadataRegistry, any time you run /saveTAS or /loadTAS,
your custom metadata is automatically stored in the TASFile in the first lines. (At the time of writing, serialization is not implemented, this is my next task)

Such a system will also be used for making extensions to a line in the TASFile itself.

Fixes

Fixed a load of interpolation issues introduced in the #179 PR.

TODO

• Why only focus on one, when you can have both! Rename copyFrom to moveFrom and write copyFrom that actually copies the methods!
• New PlaybackMetadata
  • Run author etc via PM
  • Run start location via PM
• Add event to enable playuntil
• Add event to trigger printing the author name at the start of the TAS
