Add Gen 9 BSS Factory

[LegoFigure11]

This pull request adds Gen 9 BSS Factory.

Sets by @NO-VED and the rest of the BSS Factory team. Full credits can be found in the forum thread that will be made public once the format goes live.

Apologies if there are any formatting or code style issues, I couldn't get eslint to play nice on my machine. Passes all tests but if there are other issues please let me know and I'll try to amend them in the coming days!

Addressed all except the Roaring Moon set that I'm waiting to hear back on still

Sets were expanded/shrunk automatically by my linter based on line length, I've changed them all manually but it's gonna make maintaining this file a PITA. Is it really necessary? I would argue that it's more readable if they're all expanded anyway, but that's not my call to make.

Made all requested changes @livid-washed

[LegoFigure11]

I do believe that's everything! Ready for merge, or further review if anyone else wants to take a look.

Can you also update the /battlefactory help command to indicate support for the latest generation?

[LegoFigure11]

Sure! I believe Mathy is working on updating the command.
