Can't import other TypeScript files without compiling them first

[mihe]

If you want to import a file that isn't a "TBP file", or you can't/won't use the import { TBP_Foo } from 'UE/TBP_Foo' syntax, then you're currently forced to continously compile the TypeScript file to JavaScript.

It would be nice to somehow get rid of this requirement and only ever deal with TypeScript files, kinda like ts-node.
