Add a third stat

[chadrien]

Hey 👋

It would be nice to have the option to add a third (or even more?) stat for which to configure caps. My use case is for blood dk where it would be nice to be able to set these 3 stats:

• hit
  • at most melee hit cap
• expertise
  • at least soft cap
• haste
  • at least 1423
  • at most 1423

(the at least/most combination being used a workaround to set an exact value).

I took a quick look at the code and saw that it's currently pretty hardcoded to only have 2 stats and didn't manage to quickly get a third working, but with some pointers I could also work on PR if it can help :)

This was one of the first things I looked into when taking over this project and I just don't think I can make it work. The algorithm is just too complex for a single-threaded game like WoW. 2 caps already causes the game to freeze up for my blood dk and just 1 more cap would require optimizations I don't know if I have the time to make and the specs that would even utilize a 3rd cap for this short expansion is maybe 2 or 3.

Also btw, there really isn't an attainable haste cap for any death knight spec. If you're going for haste, get more haste.

Reopening as this might actually be possible with the recent optimizations
