Setting house private / public access

[NotAdam]

Currently unable to change the access level of an estate.

The packet that retail returns with 'flags' to show on the UI needs to be figured out as that is the main blocker here.

The unknown u64 in FFXIVIpcHousingShowEstateGuestAccess is what shows the flags in the ui:

Sapphire/src/common/Network/PacketDef/Zone/ServerZoneDef.h

Lines 1772 to 1777 in 239a988

	struct FFXIVIpcHousingShowEstateGuestAccess :
	FFXIVIpcBasePacket< HousingShowEstateGuestAccess >
	{
	uint32_t unknown[2];
	Common::LandIdent ident;
	};
