IZY Weapon Pack Unofficial V3.0 Port

========================================================
Izayo WeaponPack - 7D2D V3.0 PATCH - v13
========================================================
This release fixes every reproducible bug reported on the mod page.
Two of them turned out to share a single root cause each.
1) FIXED: Weapons firing until the magazine is empty, and weapons that
permanently say "You cannot use that at this time"
(Bug reports: "Battle Rifles stuck trigger bug", "ScarH, m249, Mini gun,
all say You can't use this at this time")
Root cause: seven hidden IZY buffs set BurstRoundCount to 999 or 1000.
That was Izayo's way of faking full auto in an older game version. In V3.0
BurstRoundCount means exactly what it says, so the weapon fires an
uninterruptible burst of 1000 rounds: it empties the whole magazine and
the fire animation locks up.
Worse, those buffs are hidden, permanent (duration 0) and survive death.
They live on the PLAYER, not on the weapon. If the RemoveBuff is ever
missed (unequip, death, relog), the player is left permanently broken on
EVERY weapon. That is why reloading the game, spawning fresh weapons and
scrapping them did not help anyone.
In V3.0 the correct values are the ones vanilla itself uses:
modGunTriggerGroupAutomatic -> BurstRoundCount 0   (full auto)
modGunTriggerGroupBurst3    -> BurstRoundCount 3   (3 round burst)
modGunTriggerGroupSemi      -> BurstRoundCount 1   (single shot)
All seven buffs were corrected to the value that matches the mod they are
attached to. Note that Izayo had copy pasted 999 into the burst variants
as well, so 3 round burst was broken too and is now fixed for the first time.
2) FIXED: Full auto and burst trigger attachments are usable again
(Bug report: "cant add full auto attachments to any weapons")
The v2 port fix blocked the Full Auto and Burst trigger group mods on all
IZY weapons, because installing them made the guns mag dump. That was the
BurstRoundCount problem above. With the root cause fixed, the block is
remo…
