fix: Added missing model definitions for statistics

[jassent]

Fixes

Resolves: #624

Fixes these statistics models: Twilio.Rest.Taskrouter.V1.Workspace.Worker.WorkerStatisticsResource Twilio.Rest.Taskrouter.V1.Workspace.Worker.WorkersCumulativeStatisticsResource Twilio.Rest.Taskrouter.V1.Workspace.Worker.WorkersRealTimeStatisticsResource

The prior models are missing definitions for statistical subresources that cause deserialization to return empty/null. Other statistics models are impacted by this same issue. Suggest that developers check for other statistics definitions using object instead of a strongly typed object.

The changes are to generated code so we'll have to make changes in the generator. We have this on our internal backlog (DI-2274)
