hf mf dump error handling, revive hf mf chk d option, provide known keys dictionary...

- hf mf dump: abort on unrecoverable errors. Don't create file dumpdata.bin in this case.
- hf mf chk: re-enabled and fixed option d (dump keys to dumpkeys.bin).
  if there are unknown keys, write 0xffffffffffff instead to the file.
- provide a default key dictionary file for hf mf chk (default_keys.dic). Contents taken from
  mf_default_keys.lua
