• Simple shell script to invoke the bindings generator in generate-bindings.sh
• Simple shell script to invoke the build process in one step in build-rayjs.sh

Changed

• Upgraded raylib to 9a8d73e
• Upgraded raygui to 82ba2b1
• Upgraded quickjs to 6a89d7c
• Generated new bindings
• Upgraded all packages of the bindings generator
