Modified algorithms to use futures contract objects directly instead of accessing their Symbol property.
Removed unnecessary import statements and redundant lines in various files.
The delisting time is handled by the DateChangeTimeKeeper now, so there is no need for the SubscriptionDataReader to do any special logic for it.
This was preventing the new tradable date events to be emitted after the delisting date in some cases, like when the day after delisting is not tradable

base class.
- Updated unit tests.
- Added a new regression test to validate the latest computed value.

* First draft of the solution
* Add regression tests
* Improve solution and add unit test
* Address suggestions
* Improve unit tests
* Nit changes
* Fix regression algorithms
* Default Data to null for ETFConstituentUniverses.
The data collection will be assigned only if needed. This allows data column to be filtered from dataframes since it will always be null for all constituents.
* Make base data collection aggregator reader fall back to BaseDataCollection
After instatiating the collection type, fall back to the base BaseDataCollection to aggregate data if the type is not a base data collection.
* Minor change
* Minor change
* Update pythonnet to 2.0.41
* Ignore data column for every flattened universe dataframe
* Filter empty collections columns in data frames
