Saving player inventory

[stefnotch]

When Noita crashes, and then restores its data, it's usually a minute old or so. Combined with this mod, this can lead to the loss of wands/spells/items

Steps to reproduce

1. Put wand in bank
2. Wait until Noita has definitely saved
3. Take wand out of bank
4. Very quickly crash Noita
5. Start Noita back up, and it'll ask if it should restore the save. However, in the save that it does manage to restore (from step 2), the player does not have the wand, and neither does the Noita together bank.
