Incorrect typings for index.d.mts

[JAD3N]

I was just updating some dependencies of some of my projects and noticed I was getting a new error with the latest eventemitter3 release.

EventEmitter' cannot be used as a value because it was imported using 'import type'.

The index.d.mts file seems to be re-exporting only the type of the EventEmitter class, so TypeScript will not treat it as a value that can be instantiated.

@lpinca Since the new release is incorrectly typed, I've submitted a new pull request to fix the issue.

i got error TS2306: File '.../node_modules/eventemitter3/index.d.ts' is not a module.

@MohammedFaragallah I've made some changes to the PR, do you still get any issues?

Hey there, adding to the discussion with a type error linked to quill due to this version; if this change in API is expected, please ignore this, as it's on quill's side.

Fixed by #282.

[JAD3N]

@lpinca There still seems to be some issues, I'm having the following problems:

• Cannot access typings such as ValidEventTypes or EventListener (probably to do with TypeScript not re-exporting namespace alias types correctly).
• Trying to refer to EventEmitter as a type causes an issue where TypeScript thinks it's only a value and cannot be referred to as a type.

I think it might be safer to duplicate the declaration files as initially done in #282 to preserve the surface API (at a cost to a slight bundle size increase) or rollback the typing changes to prior #279.

[lpinca]

Ok, I will revert 7ec84d9 and b64d6b7.
