  Metadata for ORPort cells.

  Unused padding are **not** used in equality checks or hashing. If two cells
  differ only in their *unused* attribute they are functionally equal.

  The following cell types explicitly don't have *unused* content:
    * PaddingCell (we consider all content part of payload)
    * VersionsCell (all content is unpacked and treated as a version specification)
    * VPaddingCell (we consider all content part of payload)

  :var bytes unused: unused filler that padded the cell to the expected size

  Command concerning a relay circuit.

  Our 'recognized' attribute provides a cheap (but incomplete) check for if our
  cell payload is encrypted. If non-zero our payload *IS* encrypted, but if
  zero we're *PROBABLY* fully decrypted. This uncertainty is because encrypted
  cells have a small chance of coincidently producing zero for this value as
  well.

  :var stem.client.RelayCommand command: command to be issued
  :var int command_int: integer value of our command
  :var bytes data: payload of the cell
  :var int recognized: non-zero if payload is encrypted
