[Feature Request] Add identifier to TITSHitEvent when using TITSThrowItemsRequest

[dennisrijsdijk]

Currently, it's not possible to reliably know if a hit belongs to a specific ThrowItemsRequest, if it even belongs to any at all. To solve this, there should be some metadata reflected in both the Hit event, as well as the ThrowItemsRequest.

Ideally, this would also be added to TITSTriggerEndedEvent and TITSTriggerActivatedEvent
