Version 0.2.0

• Miscellaneous registry updates
• Bring stix-generator back to compatibility with the stix2 library
• Add new infrastructure-type-ov values , Incident object for CS03
• Use real values for path_enc
• Add Artifact.decryption_key co-constraint
• Add shortcuts for TLP markings to default registry
• Change the STIX timestamp semantic for the object generator to
  generate timestamps with at least millisecond precision.
  Coconstraint satisfaction is changed to be done at full microsecond
  precision. So if "ts1 > ts2", ts1 could be as little as one
  microsecond larger than t2.
• Change version-related property specs of malware-analysis SDO spec to generate strings
• Pass the SCO type enum into generate() directly instead of
  manually picking a specific type first. The generate()
  implementation handles type selection automatically!
• Add a "parse" setting to STIXGenerator's config, to enable/disable
  parsing to stix2 objects, analogously to the change to
  ReferenceGraphGenerator.
• Fix the observable-container semantic to switch off parsing
  in its ReferenceGraphGenerator instance, to ensure generated
  objects are plain JSON-serializable values.
