Weapons should use the IFrames of their randomized Animation

[radzo73]

What? Currently, if you get a Spear with the Vamanway animation, the hitbox will be as fast as you expect it, but the enemy will still only take damage every 31 frames, instead of the Valmanway's 12 frames.

How? Probably in the same way the weapon animations are randomized (using bit 17,1 if I'm reading the DSVEdit correctly). If the vanilla IFrames are shorter than the randomized animation (e.g Kaiser Knuckle uses Axe animation), then it should use the vanilla IFrames.
