OARIS2 — new Optional attributes added to sensor_track_type

new Optional attributes added to sensor_track_type, to include:
• track_quality
• time_of_first_detection
• time_of_last_detection
• priority
• amplitude
• activity_id
• sensor_function_id
• observed_function_id
• equipment_id
• platform_id
Some appear to be quite low level and applicable to plots rather than tracks. It is also not clear what some of the values are. The last 5 are not documented in the IFS to assist.

Document the mapping of associations in the DDS and GraphQL PSM

All these attributes are optional and whilst not expected to be applicable to (for instance) radar tracks generally, they are applicable (and indeed required) to support the data models of some of the additional sensors scoped by OARIS v2.0 (e.g. EW).
The PSM mapping sections (within section 8) do not discuss the mapping of (by reference) associations. This should be added, which would define the semantics of these attributes in the PSM. (Each of the attributes already has documentation in the PSM in the Beta version).
