support nested claims

[juliantaylor]

some oidc providers like for example https://github.com/dexidp/dex produce jwt's with claim fields nested.

For example:

{
  "iss": "..."
  "federated_claims": {
    "connector_id": "ldap",
    "user_id": "userid"
  }
}

As far as I can tell this module does not support these claims for e.g. Require jwt-claim or AuthJWTAttributeUsername

Would it make sense to add support for these type of claims in this module?
E.g. via federated_claims.user_ud

Hello,
Yes it would be a great improvement. As I have no time to spend for this, some help would be great.
