v1.4.7-beta Improve Loading Times of SV maps + Other Bug Fixes

Improved how heavy-SV maps are loaded. They should now load ~6-10× faster
SV maps that previously caused multiplayer disconnections should now be able to be played in multiplayer
Fixed the decouple input detection option to work in the tutorial, autoplay, and replay. It still remains off/false by default but this will change in the future after more tweaking
Other behind the scenes clean-up and work
