Describe the feature

Might need a lua binding or lua function to check if an actor is covering a target. Currently this is handled for auto attacks in core but will be needed for lua auto attacks, mobskills and eventually weaponskills once we get around to reworking that.

Use cases:

• https://ffxiclopedia.fandom.com/wiki/Valor_Surcoat
• Possibly action modifiers (Things like simplelog addon on retail can tell when a hit was intercepted by Cover)

[zach2good]

I probably wouldn't make a binding for this, since the check for cover can be a little bit computationally expensive. More likely would be populating it on the attacker/defender's behalf at the beginning of the attack round (like we currently do) and piping it into that Lua function - rather than having it calculated on demand.

Try with this commit sruon@ffe5fb3

 if bit.band(action:getModifier(target:getID()), xi.action.modifier.COVER) ~= 0 then
      -- intercepted by cover
  end

I assume this isn't going to be enough because there's nothing tying the covered to the coveree but I can't do much more without an actual broken lua-side implementation as reference.
