Just like how removeMinter() doesnt have the whenNotPaused modifier, it would be very beneficial useful (eg. when a hack / rug pull occurs) to allow users to revoke allowances and cancel authorizations whilst having transfers paused.
Remove the whenNotPaused modifiers for the cancelAuthorization() and decreaseAllowance() functions.
