Fix type export

[alecmev]

Proposed changes

This package currently works in Node.js because it's bundled, so there are no relative imports, and in "moduleResolution": "node" TypeScript (the default) because it doesn't care about the file extensions. But now there's "moduleResolution": "Node16" which does enforce the presence of the extensions, and there are relative imports in declaration files, so it breaks.

Builds on top of https://github.com/nfroidure/svg-pathdata/pull/70.

@alecmev thanks for this. I'm currently moving all my modules to ESM so I'll just check if it suits the way I did it in my other repos. I think I'll have some time to review it in a week. In the meanwhile I asked a review from other contributors.
