Simple mod to prevent the game from showing multiple perk icons for the same perks, and instead show a count of how many times the perk has been picked up.

Please be aware, this mod overwrites the perk_pickup function found in data/scripts/perk.lua and will not be compatible with mods that also change this particular function.
Perks, when picked up, add a child entity to the Player which holds the perk icon, but now also tracks the number of times the perk has been picked up and adjusts the name (when hovering over the perk with the mouse) to reflect the count if it's above 1.

I'll try to keep this updated as Noita does, if need be, and might also try to represent the count through GUI text elements (But that's later).
