Migrate @turf/buffer to TypeScript, ignoring errors

[mfedderly]

I'd like to do this more properly, but that will require a major version release.

In the meantime, we can do a low-effort job that gets us migrated away from Javascript-first packages and consolidate on TypeScript instead to simplify some of the build tooling.

Thanks @mfedderly. One more hurdle down.

Hey, this is a fantastic effort. I know the plan is to move away from jsts, but any chance that in the meantime #2937 could get rolled into this update? I'd be happy to re-do the PR in whatever typescript file comes out of your work 🙂

@plymer I'm trying to focus on #2991 instead of this, and I'm hesitating to expose these configurations until we know we're settled on a library that does provide this. But I am intending to add this eventually.

Unfortunately I'm less convinced that clipper2-ts is a library we want to depend on going forward, so I might go and port clipper2 from scratch myself before we can land that.

Cheers, I appreciate the update and the roadmap ❤️
