PreHooking protected functions

[Ayantir]

Even if it's really simple, it's not in the esoui files, so ..

--[[
ZO_PreHookProtected is a rewrite of ZO_PreHook. It accepts Protected functions.
IsProtectedFunction(existingFunctionName) will still return true even if existingFunctionName is not called
Calling existingFunctionName() will work, it will call your function and depending on your code will run the prehooked function
Calling CallSecureProtected("existingFunctionName", arg1) will work, it will call the original function only. You won't be able to "fake" other addons if they're correctly written, but mainly ESOUI code.
Don't hook a non-protected function with this PreHook or game won't load
]]--
function ZO_PreHookProtected(objectTable, existingFunctionName, hookFunction)
    if(type(objectTable) == "string") then
        hookFunction = existingFunctionName
        existingFunctionName = objectTable
        objectTable = _G
    end
 
    local newFn = function(...)
        if(not hookFunction(...)) then
        
            if IsProtectedFunction(existingFunctionName) then
                return CallSecureProtected(existingFunctionName, ...)
            end
            
        end
    end
 
    objectTable[existingFunctionName] = newFn
 
end

Doing this will mainly prehook ESOUI code and your own addon, so consider that the esoui code may not run because of another addon doing something else instead.
