Typescript Support

[Omixxx]

hi guys, i really appreciate your work!!

Do you think it will be possible to officially support typescript?
I have already looked at other issues in this repo but it seems that there is currently no solution

Could this be a good starting point?

See issue #276

Personally I'm not going to add typescript support to p5play but if you'd like to do it, I'll try to help you. I've never used typescript before so I don't know what a good starting point would be.
