Feature request: Auto add entity you're looking at to blacklist

[darchitectlp]

This is a QoL feature request, and I'm not sure if it's worth the effort, but as a pack dev, I'd love it. When you're looking at an entity, it'd be nice to have a keybind to hit to auto-add that to the mod's blacklist. Mimics, ambient mobs, etc.

Thanks!
