Proofreading Wild Caught Seafood XML mappings

[pvutran]

🎉 Issues resolved:

• The <AggregateEvent> was probably referring to the GDST CTE, but in EPCIS we have: <AggregationEvent>
• There were few typos:
• • Static Master Data - reference to vesselName instead of vesselID.
• • Static Master Data - missing mentioning of urn:epcglobal:gdst#gpsAvailability.
• • On-Vessel Processing - using the wrong namespace for vesselPublicRegistry.
• • Few occurrences of radeItemConditionCode instead of tradeItemConditionCode.
• • Few occurrences of EPCIX instead of EPCIS.
