Better ESM compatibility

[christian-bromann]

This package currently is written as CJS module. The ecosystem however is moving towards ESM and many frameworks too. It would be beneficial for not only users of also adapters of this package to have it support ESM natively and provide a CJS export for backwards compatibility.

I wonder in general if this package will still be maintained moving on?

Would also like to see the use of the builtin fetch and formdata instead of using got and form-data

Here is the challenge: I am not a JS person, but I can find time to work on this in the next weeks. I need someone to lay down here what needs to be done with some level of detail. Could anyone give me a hand?
