feat: add support for breakout rooms

[marcos-cereijo-pexip]

Change also the message overlay in all the breakout rooms.

Adding a selector to change between:

• All rooms.
• Main room.
• Breakout room 1
• Etc.

Nice!

A couple more comments:

• you can get rid of the breakoutRooms.ts file and you can just hold them in the index file and pass them as a prop to handleSubmitMessage as they are only used there
• for the plugin.ts, you can just export let plugin and assign it in the index, and avoid the getters and setters, usually its a good practice but its a bit of an overkill here (IMHO)

@TsvetozarTsonev , I changed the part related to the breakoutRooms, but I cannot do the same with the plugin (or I don't know exactly how to do it). If I import the index.ts in another file, it's triggered twice.

@TsvetozarTsonev I modified the code and now I export the plugin variable directly.
