Extend contains/containedBy/overlap to be used in joins/embedded filters

[wiesson]

Feature request

My use case is that I'd like to have the "in" operator but with the function of an "AND". So use-case is - get all posts that have tag1 and tag2 (both)

Table structure

posts (id, title)
post_tag (post_id, tag_id)
tags (id, title)

Is your feature request related to a problem? Please describe.

That's not a problem, I just can't use the feature I would like to have 😅.

Describe the solution you'd like

supabase.from("posts")
  .select("*, filterTags:tags!inner(*), tags(*)")
  .contains("filterTags.id", "(1, 2)")

Describe alternatives you've considered

Two alternatives I'm considering

1. A rpc method, but I'd like to dynamically filter my posts
2. Change the data model so that each post holds an array of tag ids. This looks like a clean solution to me, but it's a trade-off (as always).

Also given the fact, that "in" could be used with embedded resources, I thought it's possible (and nice infor the sake of completeness) for contains as well.
