fix fischl oz conditional breaking & oz spawn from q

[k0l11]

fixes #608

• replaces the fischloz status with a bool
• changes the semantics of .fischl.oz: instead of specifiying the amount of frames it's still active for, now it instead just specifies whether oz is "active" or not (similar to .albedo.elevator)
• fixes Oz spawn on Q: Oz should spawn at the end of animation, but he always spawned at the earliest cancel before.

	fischl skill;
	if .fischl.oz == 0 {
		print("shouldn't happen");
	}

I've replaced the oz status with a bool that gets used for her custom oz conditional and fixed the incorrect Oz spawn on Q.
