Fix import errors while using TypeScript+ESM

[alula]

Should close #77

@alula can you run npm run build and confirm that the package.json in build/ contains these? cborg is still using https://github.com/mikeal/ipjs to cross-compile esm and cjs but it does its own funky things with package.json, and I suspect it's going to be stripping out these fields. We could either fix it in ipjs, or just ditch ipjs entirely and go esm-only, which is a TODO I have here anyway.

ah, it even fails in CI: https://github.com/rvagg/cborg/actions/runs/5675282092/job/15666542079?pr=86 sad

I'm going to pull the trigger on #91 soon and cut a 3.0.0 that drops CJS, and in the meantime skip a compile step completely and ship the types as they are. You could help by installing cborg@3.0.0-alpha.1 and seeing if that (a) works and (b) solves your problems.

should be fixed by 3.0.0

Sorry for late response, 3.0.0 works fine for me!
