Closes #135.

I tested this locally and it works as expected in my project. I also added a new test which fails on develop but passes after these changes.

I didn't fully understand how the tests are structured/split up; I'd be more than happy to adjust things here in response to feedback.

For context, the idea behind the smoke tests here is to test with minimal number of child processes; the other tests are slow primarily because it spawns so many children.

Can you move this inside import-from-js.js?

I can, though that will require adding --tsconfig tsconfig/tsconfig-allowJs.json to that test's arguments, at which point I think there wouldn't be any tests that cover the case where TS resolution rules aren't followed. If that's good with you, I'll do the move and delete the allowJs in tsconfig.json test.

Ah good point, let's keep it this way then. Thanks for catching it!

Make this allowJs or something more unique that can be matched from within the 'from .js' test

Really appreciate this PR, thanks @nwalters512 !

BTW I had a vision to leverage get-tsconfig like this https://github.com/esbuild-kit/cjs-loader/pull/34/files but I think there are other problems with that approach and this is a good solution for now. 🙌
