Game Migrated to WebGL

Hey all - now that the game jam is over I have updated the game to fix the performance issues by migrating the code over to use WebGL with the pixi.js library. Also added a loading screen that will show the progress of the downloading the assets from itch. This will alleviate any issues that were previously seen where some players couldn't get the game to run because the code was running before it downloaded all of the art assets.

Thank you again for checking out Where's Spring? and your continued support.
