Types for Defold Extensions

[thejustinwalsh]

Support type definitions for extensions.

• Ideally these types would be opt-in in your .tsconfig file, and not automatically included.
• Library names should match the pattern of the library include so that there are not additional steps in getting type definitions to function.

Approach

• Use the ts-defold key in the package.json to point to the main *.project file for the Defold app.
  • default to app/game.project if not present
• Scan the *.project file for [dependencies] and generate the types from the included documentation in the extension package.
• If no types are available scan the ts-defold/extension-types repo (naming TBD) to check for types.
  • If these types are available a message about how to include them in your .tsconfig and package.json should be emitted instead.
  • We may also want to simply not generate types if these types are explicitly defined. There may be user-contributed types that work better than any auto-generated types.

Alternative implementation available here: xtgen

I consider @thinknathan's xtgen the best solution.
I have yet to make plans to pick this work back up in the near or distant future.
