In GameItems::setAllowedBurningAddresses the admin can update the allowedBurningAddresses mapping.
This mapping is used to check if the msg.sender has permission to burn specific amount of game items from an account. This can happen through the burn function.
However setAllowedBurningAddresses() works only one way. I mean that the admin can give permission, but not revoke it.
Imagine the following scenario. Admin calls setAllowedBurningAddresses with wrong address. Now this address has the permission to burn any token from any user. Now no one can remove the wrong address from the mapping.
Use adjustAdminAccess function as an example:
So the new setAllowedBurningAddresses function should look something like this:
Now even if the admin sets the wrong address, he can immediately change it.
