* Adds new unit tests for BenzingaNewsJsonConverter
* Fixes issue in BenzingaNewsDataConverter where we would
write data in local time, resulting in non-UTC times from
the deserialization in BenzingaNews.Reader(...). Unit tests
were added for this issue as well
* Write files by `UpdatedAt` date instead of the `CreatedAt` date
* Added ability to append to compressed files if file does not exist
* Cleaned up code as per review
* misc. documentation changes
* RSS converter now lives at: https://gist.github.com/gsalaz98/b87992cd5a5a214d01c63dbbefbbf12c
* Removed BenzingaNewsFactory as it is no longer needed
* Cleaned up code as per review to make this more maintainable
* Included new documentation
* Filter articles with no Symbols from being written
* General code improvements (duplication reduction, etc.)
* Make Benzinga News Converter more efficient (and cleaner!)
* Implement JSON converter for serialization/deserialization process
* Fix bug where duplicate symbols would be added to news.Symbols
* Modify algorithm strategies
* Cleaned up code inside BenzingaDataConverter
* Added more documentation to potentially confusing bits around the code
Previously, we would be storing Benzinga time in local time (i.e. with
about a 7hr offset from UTC since I'm in Pacific Time). But now, we
instruct Json.NET to serialize and deserialize dates as UTC.
Additionally, because the data resolution was not set to `Second`,
EndTime would be rounded down with `Time` to the closest minute. We
fixed that by specifying that the data is in `Second` resolution.
* Fixes issue where tickers with no exchange would be skipped
* Fixes issue where tickers that were ETFs were not processed
* Added additional logging
* Removed code duplication
* Reworked Clone method to be more efficient
