What does this pull request do?

This PR adds the waking the beast Ifrit BCNM fight. This is the first in a series of PRs for adding WTB. Note that this does not add the actual quest so players cannot yet enter the BCNM fight, as my plan is to add all of the BCNM fights before a final PR that adds in the quest. Also note that the commented out -- mob:setMobMod(xi.mobMod.SKIP_ALLEGIANCE_CHECK, 1) will be enabled once this related PR that adds the specific mob mod is merged.

I am not sure if this should be marked as experimental or not?

The info for the PR has been taken from a variety of captures and retail videos including:

• General behavior, mobskills, HP, immunities, res ranks, and MDT (here, here see capture logs as chat log cutoff)
• Elementals refocusing hate on avatar target periodically (here)
• Elemental En-Plague Power (here)

Steps to test these changes

As a GM go to the BCNM and enter the fight and fight the mobs

I am a big fan of ternary expressions, but this is probably a personal preference because I hate if statements ha. Curious what others think though. More for my curiosity than anything (code is perfectly fine).

spellTarget = math.random(1, 2) == 1 and mob or elemental

Yeah, I like the if statements mainly for readability, especially for new devs or contributors since this is in Lua.

Looks reasonable to me.
