feat: add Minesweeper channel

[rshigg]

Description

This PR adds a minesweeper channel. I know it's not exactly a mainstay of the speedrunning community but it is a personal favorite of mine 😅

Current features:

• Donations under a certain amount (currently 50) cause a mine to be flagged
• Donations above that amount cause a randomly generated cluster of tiles to be revealed
• All donations cause the little face at the top to change

I'm currently on the lookout for another font to use, this one is temporary.

Would love some suggestions on how to make the channel more exciting between donations

[VodBox]

Also, would like to clarify whether it's intentional that there is no credit being applied to this channel? I understand with the current design, all corners are currently occupied, but if you're wishing for a credit to show, I'd consider worth shortening the grid just slightly for that.

@VodBox I've persisted the grid state and used the shortName field from currentEvent. I've also added credit, which covers 3.5ish tiles in the bottom right (screenshot bellow) but I think that should be fine.

Also after some thinking I agree with you that the channel doesn't necessarily need to do anything between donations. All of the ideas I had come up with definitely would be too distracting.

I added two small features

1. Every 5-10 seconds change a random mine to a question mark https://github.com/GamesDoneQuick/gdq-break-channels/pull/23/commits/f6c7075174fc56bc3c84468a8058ab83ea776937
2. Whenever someone subscribes change to a heart eyes face https://github.com/GamesDoneQuick/gdq-break-channels/pull/23/commits/ebe9064d1239859b87089e048bf9ebdd75abb748

Feel free to reject either, just thought they might be fun changes that are not too distracting.
