[SUGGESTION] Display Entity Billboarding Options for VFX

Title; an option like VFXBillboard or a parameter billboard= to set the billboarding of the VFX (FIXED,CENTER,HORIZONTAL,VERTICAL) would be great.

Believe that it's already an option in MythicMobs, having it supported in MEG would make things easier. https://git.lumine.io/mythiccraft/MythicMobs/-/wikis/Mobs/DisplayOptions#billboard
