Feature- Support tempo changes

Note block studio has a feature to place tempo change events in songs, but NoteblockAPI doesn’t seem to support them (this setting is fairly hidden in NBS, so i wasnt suprised it wouldn’t work in NoteblockAPI).

Many songs just don’t work too well without this, usually having to settle for the average BPM (which doesn’t work well for songs with huge changes). I feel there should be some support for them.
