* Normalize universe data frames

Universe and (generically BaseDataCollection) data frames are not normalize and unpacked into a data frame, instead of just creating data frames with the universe lists within it

* Fix unit tests and algorithms to expecte new universe dataframe format

* Fixes

* Add PandasConverter.DataFrameGenerator class

* Pandas data frame generator class fixes

* Add comments

* Housekeeping

* Add attributes to mark classes and properties for pandas processing

* Improve pandas properties expanding

Allow and handle duplicate names

* Use PandasData generalization for Lean common data types

* Add points time as column when converting base data collections to data frames

* Cleanup and minor changes

* Minor change

* Pandas data to get type members on demand

* Move Pandas helper classes to their own files

* Minor changes

* Add flatten argument to python history api

This allows users to decide whether they want fully expanded dataframes for universe and other collection data types. Else, master behavior is kept

* Adding missing changes to last commit

* Update Pythonnet version to 2.0.40

* Add flattent argument to algorithm's OptionChain api

* Minor changes

* Housekeeping

* Minor changes

* Bug fix skipping data collection data points

* Add comment

* Set correct exchange time to OptionUniverse instances

* Address peer review and cleanup

* Cleanup

* Minor changes

Jhonathan Abreu 0a9dc2c71c QCAlgorithm's OptionChain() api refactor (#8334)
* Fix pandas converter to handle list of data with different symbols

* Properly convert list of data into dataframe

Take into consideration data for multiple symbols in the same list

* Cleanup

* Index dataframes by symbol object instead of SID string

* Add symbol equality operator to compare against object

* Exclude "ID" from option chain dataframe

* Minor fix

* Add greeks columns directly in option chain dataframe.

Also add pass-through properties for greek values in OptionUniverse

* Some cleanup

* Minor fix

* Add new QCAlgorithm.OptionChains() method

- Use OptionChains as output
- Add DataFrame to OptionChain and OptionChains
- Rename Greeks classes
- Add ISymbolProvider for classes that have a symbol (IBaseData, OptionContract)

* Unify QCAlgorithmOptionChain API

Also refactor OptionContract to handle: (1) Actual market data and option price model data, and (2) OptionUniverse data

* Pass symbol properties to OptionUniverse option chain from algorithm

* Format OptionContract for dataframe

* Minor fix

* Add multiple option chains api regression algorithms and other minor changes

* Address peer review

Add NullGreeks class: keep ModeledGreeks as internal as possible

* Minor fix and add PandasConverter unit tests

* Peer review: Non-thread-safe Lazy for Python

* Handle Greeks unwrapping by PandasData

* PandasData cleanup

* Add data and other minor changes

* Unit test fix

* Update Pythonnet to 2.0.39

* Cleanup

* PandasData handling children class members

Address peer review

* Fix: indexing symbol conversion in pandas mapper

* Fix pandas mapper to convert string keys to symbol only when necessary

* Cleanup

* Cleanup

* Add PandasColumn python class to handle proper indexing

This allows propery hash and equality between Symbols, C# strings and Python strings

* Minor fixes

* Symbol cache improvements

* Minor fix for cache miss

* Revert PandasMapper reserved names and improvements

* Minor fix

* Revert reserved names

* Minor fix for Symbol equality operators
