Add mod parsing support for 3.26 Vile Bastion

[Ariacell]

Description of the problem being solved:

Implements support for the upcoming custom mod on the new version of Vile Bastion in 3.26:

ESRegen/sec was already supported, but es per spell block was not (at least that I found)

Hope the flag name is okay, could also be changed from
MaximumEnergyShieldIncreasedByChanceToBlockSpellDamage -> EnergyShieldIncreasedByChanceToBlockSpellDamage
if preferred!
Name changed 👍

Steps taken to verify a working solution:

• Validated with 0 intelligence character that energy shield is correctly impacted by the custom mod with both item based es and custom config es/spell block mods
• Checked for no crashed in the calcs breakdown section to confirm the source is mapped correctly
• Added unit tests for the calculation based on the baseline build with 75% spell block cap

Thanks for adding the tests, this is great! Let's also change the wording to remove "Maximum" and better match the other mods like it.

Thanks for the quick feedback! Moved/renamed 😃

I'm assuming the inital modcache update is okay by the way? I thought it was surprising that some mods were removed when I refreshed with a fresh checkout of dev, so I've kept that change split out in 4074bb7 just in case I've messed with it somehow.

Yeah, someone likely didn't regenerate the ModCache and the PR was merged. It's a recent change to our process so I'm not totally surprised. It definitely didn't come from your changes though
