Make Yolona outer damage ignore shields

[lL1l1]

Issue

Yolona's outer ring damage (7500) is lower than T3 shield HP, so it gets fully absorbed and deals no damage.

Making the ring damage deal damage to shields is not viable because ring damage is repeated as the nuke shockwave travels, so it would deal many instances of 7500 damage to shields.

Description of the proposed changes

Add a new damage type for the Yolona that ignores shields.

A new damage type keeps backwards compatibility with nuclear repulsor shields because the SlowNuke used by Yolona overrides the damage type to Nuke in those mods (they hook NukeDamage.lua and replace the lua DamageArea with the engine DamageArea).

Switching normal nukes to the new damgae type would break those mods.

Testing done on the proposed changes

Nuke the paragon using the outer damage and confirm that it ignores the shield.

Doesn't this look like intended behaviour that the shield is capable of absorbing damage that is less than the shield HP?

[lL1l1]

Standard nukes bypass shields for balance reasons, including the miniscule outer damage, hence why it's a bit unintuitive that Yolona's outer damage is blocked by shields.
