ReviewerID() only accepts int or string despite most apis transitioning to int64 in 1.0.0

After switching to 1.0.0 the following snippet of my code broke:

mergeRequests, _, err := a.client.MergeRequests.ListMergeRequests(&gitlab.ListMergeRequestsOptions{
		Scope:      gitlab.Ptr("all"),
		ReviewerID: gitlab.ReviewerID(a.getCurrentUser().ID),
	})

Because in 1.0.0 getCurrentUser switched to int64 meanwhile ReviewerID panics unless an int or string is passed to it
