Stronger Unmaykr

The devs hate the Unmaykr for some reason so I had to take it into my own hands to make it worth existing. Should feel like a more meaningful reward for doing the slayer gates now (probably still worse than the BFG but a bit hard to top that isn't it?)

Reduced spread of side shots (3°, 6°, 9° -> 2°, 4°, 6°)

Increased damage of central shot (200 -> 250)

Removed ALL boss resistances to the weapon

Gave some of the bosses vulnerability to the weapon

Increased max Argent cell count to 100

Increased Argent cell pickup value to 50

BFG shots now cost 50 cells

Result: The Unmaykr is now more accurate, generally more damaging, effectively more ammo-efficient, and more worthy of its status as an ancient pinnacle of weaponry. Have fun tearing the Icon of Sin apart, you've earned it.

Bonus: I added some protections to stop you from accidentally switching to the BFG when you don't mean to and wasting your ammo. Not sure why there weren't there to begin with but you shouldn't have to worry about misfires anymore.
