Response dataclasses models instead of dicts

[leynier]

Working with dictionaries in the responses makes the development tedious process, it would be good if the response of the methods were dataclasses.

The types can be found in the gotrue-js documentation: https://supabase.github.io/gotrue-js

We can use pydantic as it brings validation and deserialization or else uses dataclasses and implement deserialization by ourselves.

I wait for feedback, I'm willing to work on the pull request.

Hey @leynier,

Thanks for the suggestion! I think dataclasses make a lot of sense. Please feel free to go for it.
