Better LFG Class Colors

Last Meaningful Update: 5/25/23. Changelog at the bottom of this page.

Description:
Super tiny piece of code to show which classes are in the dungeon or PvP LFGs at a glance. Reworked version of https://wago.io/klC4qqHaF, with all the RIO code stripped out, the colors made more visible, and everything made dynamic.

Recommended to use along with:
Better M+ LFG - Colored Scores and Best Keys (R.IO/Vanilla)

Performance:
Literally zero performance hit.

Troubleshooting:
I'll be notified within a few hours if you write a comment on Wago. Include an error log/detailed description and I'll try to fix anything that breaks. Note that evoker icons displaying random junk in the PvP LFG is a blizzard bug, not affected by this weakaura. The background color of an evoker will be correct, the class icon will likely be junk. Make sure you are using the latest version of the weakaura if something isn't working.

Changelog:
    * 5/25/23:
        - Added coloring to the Arenas and Arenas Skirmish LFG frames. Arenas Skirmish has not been tested at all but hopefully works (I couldn't find any groups in LFG - no idea how that game mode is supposed to work)
        - Changed the order in which different classes are displayed. Normally this doesn't affect anything, but in PvP the class icons are shown and need to match up correctly with the order. PvP now sorts with blizzard's official sorting order, and dungeon LFG will sort by blizzard's official sorting order as long as you don't have premade group filters installed. PGF uses its own sorting order, and to keep things consistent this weakaura will enable compatibility sorting to match PGF's
        - Note that there's a blizzard bug where evoker icons in the PvP LFG aren't displayed correctly, often being blank or a random class icon. My weakaura picks up evoker data correctly, but it will clash with whatever junk blizzard puts as their icon.
        - Large rework of the internals, including more dynamic support for different sizes of groups. Previously, everything was very hardcoded to only work with 5 player groups, but now it can handle positioning and display correctly with any size. Putting this coloring into other LFG frames will be easy, if needed in the future.
    * 11/22/21:
        - Fixed display issue with vanilla UI
    * 10/17/20:
        - Initial version
