Juni replay

Have Juni replay objects that record positions and animations over time over time

The ability to record replays, and save them to file essentially. Would require saving and setting of random seed. When the recording starts, it should load latest save and return Juni there, then record key input each frame. Replaying would override the player's key input with the recorded input. Will require a bit of an overhaul of input, but shouldn't be too bad. Saving recordings would be neat for speed-running, and such.
