[Feat.] Expose an interface to get current instance for instanced maps

[ClayLivince]

Hi dear devs I wondered if it is possible to have a interface or something exposed of FFXIV.Memory to allow plugin to get the player's current instance for instanced maps? (Such as Mor Dhona or Labyrinthos) I used to get through subscribing network InitZone events but on rare times it got packet loss, and I can't get correct one of it, if it can be implemented inside this it would be much more convenient for a lot of plugins to get that. Thank you!!!
