minimal support for protected / member only content

[tzarebczan]

We're close to rolling out member only content, which will be tagged with c:members-only tag on the claim. We should filter this in all categories outside of following/wild west as part of "not tags". It should be shown on following/channel pages.

For claims with c:members-only, refer users to odysee.com to sign up for memberships to view content. If we want, we can check if they are authorized to view, and then we can use the existing get call to play it back via URL signed domains.

To check if they have access to something, use this call: https://api.odysee.com/membership_perk/check

Pass: auth_token claim_id type: "Exclusive content" for static, or "Exclusive livestreams" for lives

Few questions:

• Member only content should be filtered from search, right?
• What's URL signed domains?
• Should there be some indication that it's member only before going to the file view page?
