Typescript Transpilation

[elliotBraem]

Allows developers to write widget code in Typescript. Uses sucrase to transpiles to valid BOS Lang.

• After transpile, there is big white space where the type + interface definitions used to be; while it doesn't really matter during development as these files are in /build, I think we should do some formatting before code gets deployed
• This enables Typescript so it is helpful in your IDE, but beyond that, any interfaces or types are discarded during the build process. I'd like them to be extracted and deployed on chain so they can be used by other developers and for other purposes. We could extract and use them to create JSON Schema.

It's looks good to me, yeah the spaces are weird but I don't think they'll cause a problem. Typescripts as onchain types will be amazing :)
