STIX 2.1 to MISP Attributes mapping

When importing STIX 2.1 content into MISP, Indicator objects are parsed to produce MISP attributes with the to_ids flag set, while Observed Data objects (together with their referenced SCOs) produce MISP attributes with the to_ids flag unset.

For internally-generated STIX bundles (i.e. bundles produced by MISP), the mapping is a faithful round-trip: the original MISP attribute type and value are recovered from the STIX pattern or observable.

For externally-generated STIX bundles, STIX objects are mapped to the closest MISP attribute type via heuristics.
