Add support for /announce[color] command variations

[Mm2PL]

Discussed in #4367

Unrecognized command when sending /announce with any color.
Insert /announceblue /announcegreen /announceorange /announcepurple in the options when possible. I don't know if Twitch already has the endpoint for this.

However first colored announcement support needs to be implemented. I can see this functionality being merged into a single PR if neither part is too large.

When implementing the commands, they should replicate Twitch chat's behaviour

Supporting the /announce[color] commands would be very straight forward and I could create a PR for that.
I also looked a bit into displaying colored announcements and don't know how (or if) this can be implemented because I didn't find any documentation. https://dev.twitch.tv/docs/irc/tags/#usernotice-tags doesn't even document the announcement notice in the msg-id tag which we currently use to detect announcements.

I'm ok with implementing sending, even if receiving colored announcements don't work

Here are some example announcement messages:

The tag for the color is msg-param-color.

system-msg tag is always empty, the user text is only in the message content,
msg-param-color IS NOT a hex color, don't be fooled, it's an enum of BLUE, GREEN, ORANGE, PURPLE, PRIMARY (this value means to use the color tag)

Okay, thanks for the info. I opened a PR which only implements sending the commands.

Using your information I will further look into displaying colored announce messages and open another PR once I implemented it.
