In MongoDB, clients will be able to send a collection UUID as the "namespace" of find/getMore commands. This is useful for low-level tools like mongorestore and mongomirror, so we need to ensure that the low-level operation API supports this mode.

Some options:

• Add a 'UUID' option to the opts.namespace type.
• Write UUID-specific versions of find/getMore. This might be more performant by avoiding the check for UUID in the 99.99999% of operations that won't use it.

We may want to consider if we want to allow yamgo Collection structs to be set up with a UUID or if we only want to support UUIDs with low-level operations.
