Description of the problem being solved:

Previous implementation of the Parry Debuff was not fully supported and could not be scaled.
This PR adds support for

  • Parry Debuff Magnitude modifiers
  • Parry Debuff Duration
  • Parry Range
  • Refutation (or other future skills) enabling Parry

Steps taken to verify a working solution:

  • Config Option "Enemy has Parry Debuff" can be activated with just Refutation
  • Config Option can be activated with different active skill
  • Mods get parsed
    • Magnitude
    • Range
    • Duration
  • Breakdowns show correct values and mods
    • Magnitude
    • Range
    • Duration
  • Debuff only applies if config is active
  • Debuff does not affect to spells
  • Debuff applies to attacks other than Parry itself (including minion skills)
  • If multiple skills can apply parry with different magnitudes, only the highest applies
  • Added automated tests to TestSkills_spec.lua (only for basic tests)

Adds processing of "<DebuffName>Magnitude" modifiers, in addition
to existing checks for generif "DebuffEffect" and skill-specific
"Magnitude" modifiers
- Moved the process of Debuff to `skillStatMap` as "Refutation"
  introduced new ways to gain access to parry debuff
- Changed the mod details slightly to enable better debuff processing
Parry duration hasn't been processed at all yet, and mods affecting
Parry range currently false apply to the weapon range used for the Parry
attack, rather than blocking distance
Makes it easier to reuse in other contexts. No functional change
otherwise
Includes:
- Parsing of mods
- Calculation and adding to `output`
- Breakdowns for each stat in CalcsSections
Also slight changes to calculation approach in `CalcPerform` as it
previously didn't account for debuff effect being multiplicative
Automatically tests:
- parry debuff increases damage when active
- parry magnitude further increases damage
- parry debuff does not affect spell damage

NOTE: that last one will have to be adjusted once we support the mod
that changes parry to apply to spell damage instead, but I guess that's
what the test is for...
