Added GetUser method that supports a JWT.

[AlexMeesters]

What kind of change does this PR introduce?

Adds a GetUser method with a JWT parameter. Using this to verify a user on a back end service.
Reasoning for adding it is based on this issue: supabase/supabase#147
Whereas you can do this in javascript:

const { data: user, error } = await supabase.auth.api.getUser(token)

What is the current behavior?

Currently the API is not exposing the method to fetch user data using a JWT.
I've added this method so it is exposed to the client. So it can be used on backend services to validate JWT's.

What is the new behavior?

Method in Client that allows you to fetch the user using GetUser(jwt).
Called like so:

var getUser = await client.GetUser(jwt);

Additional context

No further context. Feel free to ask questions or explain to me a better way to solve my problem if there is any.
