Optimizations, bug fixes, changes update

This update brings optimizations to the quest platform. I've optimized it so much that based on the numbers alone (Draw calls, poly count) it should run on quest 1, although that's not guaranteed as I only have a quest 2,

fixed a couple bugs

removed the couch, that was the biggest offender in terms of performance draining. it had over 400,000 triangles! I will add a different one eventually.

all objects except one have had physics disabled for performance reasons.

The next update will bring lighting quality fixes.
