Fix typing issue

[JAD3N]

The import needs to be treated as a value, not a type as a type cannot be instantiated.

[JAD3N]

There are still issues with the typings so I've converted this to a draft.

I've adjusted the typings and it seems to be working on my projects now after applying the changes.

This duplicates everything, does it work with just import { EventEmitter } from "./index.d.ts"; in index.d.mts.

I tried to do that, but I also encountered an issue with that mentioned here: #281 (comment)
TS2306: File '.../node_modules/eventemitter3/index.d.ts' is not a module.

Ok, then I think I will just revert #279.

[JAD3N]

@lpinca I've made a few changes and it seems to be compliant with the tool specified in #279 and doesn't duplicate the type definitions.

[JAD3N]

I've tweaked some things to add better compatibility with older TypeScript versions and removed the duplicated typings by adding a shared types file.

The type checking tool also gave all green, after checking via importing via CJS and ESM I don't see any issues. This PR looks good to me, if there are any needed changes please let me know!

Thank you.
