Extract HitsToHeadshot (and possibly other weapon data outside of m_WeaponInfo)

[Vergir]

Graves' weapon data exports CanCrit: true, but she can't land headshots and consequently can't crit too. There is HitsToHeadshot field that does not get exported because it's outside of m_WeaponInfo.

Exporting it would allow programmatically see which heroes can't headshot and use this data on wiki.
