Enable "filter[query]" on campaign members endpoint

Saw a couple of posts regarding this from 2019. Not being able to filter by email is extremely expensive both on the developer side and I’m sure it’s more costly on Patreon’s side forcing developers to page through all members.

The filter parameter is already enabled through the creator login and I cannot see any technical reason why the API doesn’t have the same query parameters.

Please provide a way to filter members by email so environments where OAuth isn’t viable can retrieve basic membership details.
