Enhancement: Exclude highlights in specific channels

[bxrbeq]

It would be very practical to exclude some channels from one ping you have set. Chatternio has that feature as well and it comes in handy, when you have multiple chats open, but don't want to be pinged in every channel for the same pattern.

This, but also an exclusion for highlights by users (like the chatterino highlights blacklist with Regex)
