Armored Core 6 Warning Over Heavy Melee Charge

Replaces the default heavy melee charge sound (charged_melee_full.vsnd) with the weaponry warning sound from Armored Core 6: Fires of Rubicon. I'm atrocious at listening for the normal heavy melee noise but thankfully this one is ingrained into my psyche. Does not effect anything but the charge up sfx.

To manually install, rename the vpk file to pak##_dir.vpk where ## is any set of numbers not already in use and copy the file to Deadlock/game/citadel/addons/. To uninstall, rename the file to something else or remove it from the addons directory.
