Hey @tschuehly,

I have another PR for you but I don't expect you to merge it as is because I saw you refactored a bit more in the SNAPSHOT and this is not yet as complete as you'd want it to be (missing exception handling and tests). Still I thought this may be usefull for you if you refactor it a little.

Here is a short overview:

• invite user by email using the service account, incl. meta data
• sign up users with email incl. meta data (with or without service account)
• enroll, unenroll, and verify MFA (only TOTP for now)
• low-level: runGoTrueWithResult() to be able to pass a result (e.g. I use your starter in a Spring Boot app and there is further business logic which needs the results of the service)

Have a great start into the week and keep up the great work :)
