scratch-vm with something similar to the phosphorus runtime & compiler hacked into it.

Setup

See https://github.com/TurboWarp/scratch-gui/wiki/Getting-Started to setup the complete TurboWarp environment.

If you just want to play with the VM then it's the same process as upstream scratch-vm.

Non-goals

• upstream merging into scratch-vm
• generating code to be easily read or modified by humans
• 100% compatibility with every script, block, extension
• allow modifying compiled scripts while they are running
