[Request] Add wrapper to set player anthem/banner/title

[BlueRaja]

Currently we have a method of setting items on car loadouts, but no way of setting the anthem, banner, avatar border, or player title.

As I understand it, these are stored under a special "profile loadout" which we have no way of accessing. I think(?) we need TA_Vanity wrapped, but I'm not certain how to determine that for sure.

Discord discussion here. We attempted setting all of these things on all of the car presets, but that didn't work.

Looks like someone figured out how to set anthems, but it involves manually editing the save file byte-by-byte which seems... dangerous
