feat(net): D.2b-B B-Wire — ParseViewContents (0x0196)

Browse source 
GameEvents.ParseViewContents parses the ViewContents GameEvent payload:
containerGuid + count + [guid, containerType]×count. Records
ViewContentsEntry and ViewContents added. 3 unit tests added in
GameEventsInventoryTests.cs (two-entry, zero-count, truncated).
