Currently the HistoryRequest includes information regarding the tick type, but that information is not passed to the HistoryPacket. Therefore, only the common data types for a history request are returned for history requests. This is problematic for crypto history requests that specify Trade History.

was emitting bars whose end time is equal to the start time.
Implemented a FilterEnumerator<T> privately so he can filter those out
when using non-tick data
