fix: correct monster struct base pointer for HGE multiplayer sessions

[TheNuclei]

Fixes #404

mhfo-hd.dll+0E37DD38 resolved the wrong addresses when other players or NPCs were present in the High-Grade Edition client.

Changing to mhfo-hd.dll+DC6BB9C appears to have fixed these issues, resolving the correct information at all times.

Changed 64 references to 0E37DD38 to DC6BB9C within HGE addresses.

Pointers found through CE pointer scans across multiple solo and multiplayer sessions, testing completed solo, with NPCs, and with hosted and non hosted multiplayer quests.
