RCOCOA-2051 Add Static Queries

[jsflax]

Adds support to use Codable types to query an atlas cluster, obviating the need to use the old BSON types we introduced.

@jsflax Can you please rebase this, so the CI can be executed

This is not in a reviewable state. It is a giant mess of unfinished things and unrelated changes.

[jsflax]

Some field renames and added methods snuck in.

If I remove the MongoQuery addition (it was experimental and was chatted about when the project started), what else is missing @tgoyne ?

[tgoyne]

There is a whole bunch of commented code, random unrelated changes, and very few of the new public things are documented.

Alright, I'll clean it up.
