Actually add the Pose Classifier code to Game.js (In the midst of merging, I forgot lol) and create an aserprite version of the curb ramp sprite

Added Start Scene (used scenemanager.js library which utilizes namespacing so things are just a lil bit different. BTW sketch.js is now game.js in gamejs/

Add basic player sprite funcitonality and logic for preventing player from moving onto the wrong tile types (logically the code works but functionally theres a bug lol.

Add more tile types and get sidewalk fixer and curb ramp placer tools working (along with basic tool toggling and creating a base map for level 1.

Merge Leanna's work with mine and Wu's (we had our work in a seperate p5.js web browser sketch. This includes Leanna's code for controller stuff with Wu's and my basic grid/game logic code.
