fix: ignore high mode bits passed to constructor #53

The UnixFS Spec says high mode bits not defined in the version of the spec supported by a given implementation should be ignored but also persisted to ensure forwards compatibility. The change here:

  1. Ignores high bits passed to the constructor
  2. Respects high bits read out of a protobuf though does not expose them
  3. Writes high bits back to a protobuf but only if they were read from a protobuf to begin with
