Bundle Typescript without transpiling?

[stevefan1999-personal]

I want to integrate rollup with TypescriptToLua which does not support JS imports yet, so I have to use a bundler to pack Typescript in.

However it uses Typescript types to do optimization and I wonder if that is possible for rollup to not transpile the Typescript, and instead just process the static ES modules import/export. Don't strip types.

For node_modules that have corresponding Typescript source, include them into the bundle as much as possible. That way we can ensure highest level of tstl compatibility
