[SOD] Please add runeid support for shoulder slot item

[vihorban]

Hi,

Currently the addon is not tracking shoulder runes on items. So if you have 2 of the same items but with different runes, it will track them as same items. So that`s resulting in wrong runes equipped when equipping set.
That shoulder runes were added in P7 of SOD

Example of shoulder record in ItemRack.lua
"231602:2605:::::::60:::::::::"
The similar record for head item(with runeId)
"231604:7634:::::::60::::::::::runeid:49319"

Thanks

After a brief research I realized that shoulder imbulement is not an rune from game perspective. That`s why C_Engraving lib does not recognize it as a rune.
So basically shoulders are having 2 enchantments at the same time
Zandalar spell power(2605) + Temporary: Cryomancer (7772). But in fact that teporary enhantment does not have any expiration

Made some local change for myself

if slot == INVSLOT_SHOULDER then
  return ":runeid:"..tostring(FindSpellOverrideByID(1219955))
else
  return ""
end

@vihorban in light of this project being essentially abandoned could you provide more context on where you made this change or provide a pull request / fork?
