Implement FIFO\Queue pool

[ravsii]

I don't know how exactly to do that right now in terms of API. Could be as a separate pool, or an options to NewPool()

Bro, this looks straight up copy-pasted from ChatGPT, and it's not even related to the project.

Hey, @mtnvdsk .
I could write a detailed explanation a bit later, but shortly, the problem is:
Currently we have a basic pool (pool.go) that accepts players and returns found matches based on players' elo rating. There's a how-it-works diagram in README.

We'd probably more types of pools, which will have different "match found" algorithm, so FIFO is one of them (obviously it just matches players without comparing their Rating).
