This change refactors the dump commands to inherit from a base DumpApkCommand and adds a command that prints out an ASCII image of a badger if the user wrote "badger" instead of "badging". The command is hidden from the help menu. Bug: 73535002 Test: manual Change-Id: I9bdd8a7bbf6a4282c4933e5c478f6d1d8e32d99e
