feat: Add additional filters and filter contexts

Created by: pharmafemboy

Summary

Currently filters only apply to the timeline, and there are only two options, a soft mute (which replaces the post with a "$displayName said something" prompt that can be clicked to show the post) and a hard mute (which removes the post from the timeline entirely)

Filters should be more flexible to allow for other filter contexts, such as also optionally affecting notifications, only affecting specific timelines, only applying to specific users, having expiration so that temporary filters can be applied, etc

Purpose

Adding an option to have seperate filters with different contexts and different soft/hard effects would make them much more flexible and configurable, allowing for more specific and specialized filtering

Do you want to implement this feature yourself?

• Yes, I will implement this by myself and send a pull request

This would come with performance drawbacks though as with each additional filter a new check gets added and with that new check happening on each incoming post into your timeline it would slow down arrival of notes.

So I am generally against adding more filters than necessary

Since no one has chimed in with an alternative and it seems like no one else really needs more options I will go ahead and close this.
