…rGroups (DHIS2-10625) (#280)

* fix(current-user): allow custom fields in getUserGroups (DHIS2-10625)

This allows to override fields=:all to reduce the response size.
One example is the Interpretations component, where only the group ids
are actually needed.

* feat: add method for accessing group ids directly

Current user group ids are already available from the /me response.
Add a method for accessing them directly without making any api request.
In some cases the ids are all is needed (ie. Interpretations component).
