Move fetchProfile into constructor params

[sampolahtinen]

Hi!

I recently discovered that if scope includes openid the library automatically calls auth0's /userinfo endpoint.

https://github.com/danestves/remix-auth-auth0/blob/main/src/index.ts#L95

I have also noticed that this endpoint is rather slow. Execution time between 300ms to 1000ms.

Would it make sense to move the fetchProfile to the constructor parameters so that users can opt in or out of it?

The thing is that if the scope includes openid, the auth0's /token endpoint returns accessToken and idToken, where the idToken already provides quite a bit user information. This information might be enough for most of the consumers and thus could avoid calling the extra /userinfo endpoint.

WDYT?
