Add channel block lists like De-Mainstream for YouTube

[toyboatcash]

Use Cases

This plugin Fixes the YouTube algorithm to remove mainstream media results from searches it would be nice if grayjay supported something similar this could be expanded to allow custom predefined list and include channels from other platforms that are not just YouTube for example https://podcasts.apple.com/us/channel/abc-news/id6442482866 & https://podcasts.apple.com/us/channel/msnbc/id6442484553

Proposal

Add blacklists for different plugins for specific channels I'm thinking something like a blacklist that can be added to grayjay with predefined lists.
