Add support for inc brand aoe after 50% attached duration mastery

[Nerotox]

Description of the problem being solved:

Adds support for the "Brands have 30% increased Area of Effect if 50% of the Attached Duration expired" brand mastery.

Adds a new config "Last 50% of attached duration?", similar to the current 25% from from the heiro ascendancy.

AoE only applies to brands -> had to introduce small changes to the AoE calc to support brand specific AoE modifiers. The inc. AoE mod is still shown in the breakdown for non-brands but it is not applied. If s1 has a clue on how to have a skill type condition in the CalcSections.lua feel free to comment.
E.g. Toxic Rain:

Steps taken to verify a working solution:

• Select a brand skill with a radius (e.g. arma brand)
• Spec the 30% aoe if 50% expired brand mastery
• Enable the "Last 50% of attached duration?" config
• AoE calcs should have 30% inc aoe for all radii (primary, secondary, tertiary).
• If a normal skill is selected then the AoE will not apply (e.g. toxic rain)

@Nerotox I fixed the PR in my latest commit. When you're adding a mod that applies to a whole skill type you can just add a SkillType check in ModParser and the AoE component will be handled correctly by the existing code
