ES module support

[Gusb3ll]

I wanted to use mqemitter with my graphql mercurius here's my implementation

but after I use it in the mercurius config I got these errors

TypeError: (0 , mqemitter_redis_1.default) is not a function

so I can't import it as an ES module, I'm wondering is there any planned support for it. Tysm 🙏

Thanks for reporting!

Can you provide steps to reproduce? We often need a reproducible example, e.g. some code that allows someone else to recreate your problem by just copying and pasting it. If it involves more than a couple of different file, create a new repository on GitHub and add a link to that.

Here's my reproduction https://github.com/Gusb3ll/mqemitter-issue

Can you simplify this by removing Nest.js? I'm not familiar with it and it makes this significantly harder to fix. A PR would also be highly welcomed.

I'm pretty sure the issue I'm running into is the same root cause wrt problems using this under ESM only. The check under https://arethetypeswrong.github.io/?p=mqemitter-redis%406.0.0 shows:

...with a suggested fix.

A PR would be ok
