add OData cast to OData query.

[mathiaac]

Would it be possible (or is there already a way to do it?) to add casting as part of constructing the OData query, as per example 3 and 4 from the official docs? https://docs.microsoft.com/en-us/graph/api/group-list-members?view=graph-rest-1.0&tabs=http

Because if I now for instance want to list all users that are members of a group I have to list all members, iterate through them and calling get on the user client and then I will of course get a bunch of 404 errs which I have to handle. Whereas if I could cast ListMembers to users then I would be set with that one call. Think this would also solve this issue. #20

Thanks for the SDK btw, replaced graphrbac with the official sdk only to discover build time went up an absurd amount.

@mathiaac Thanks for the compliment, and the suggestion. We'll definitely look into supporting this.

@manicminer Thanks! Do you have a rough estimation of when that feature potentially will be in place?

[manicminer]

We're working on a pretty big refactor at the moment that will make this sort of change much easier, so I hesitate to give an estimate however it's not something I have time for right now. PRs always welcome in the meantime however, even if for an reference/interim implementation :)
