Parse advanced copy/paste format

[Wires77]

We've long not parsed the advanced format because of its complexity and just not being worth the effort. This PR attempts to resolve that.

Things to still do:

• Copious tests outside of just some item examples
• "Unscalable value" needs to be removed
• Test with catalyzed values
• Possibly trim reminder text
• Make sure linePrefix is being reset even at the end of a section

Most of this is working, but I didn't fix copy/pasting influenced items yet, and in fact it causes an error right now after messing with adding/editing more custom mods:

Three issues remain when testing this, but they may be out-of-scope for this PR:

• Crafted hybrid mods in PoB scale their values in tandem, whereas in PoE each line can have values at the top/bottom of their range independently. E.g. A life/armour hybrid mod might have the maximum life value and minimum armour value. This can't happen when crafting an item in PoB, and thus pasted values might differ from what gets pasted in.
• Pasting in mods modified to outside of their normal range via misting or volatile vaal orb end up showing strange slider placement. This causes weird behavior when changing other slider values, as ItemsTab first sorts the mods, then realizes one mod is outside of the possible range and removes it from the item (though not from the crafting sliders, and only if it's below the range. Above the range looks like the attached image)

• The — 19% Increased suffix on a mod line is ignored unless the item has a catalyst applied. We already removed support for tailoring orbs, so this seems fine for now.
