* Memory Related Performance improvements
- Make sure we cleanup & dipose of python related objects during pandas
data generation.
- Disable memoizing enumerable use while creating pandas data frames,
since we do not require it
- Reduce unrequired object creations
- Replace concurrentCollections for ordinary locks
* Decimal parsing typo fix
- Add StreamReader Reader for Tick data type.
- Adding stream reader GetString extension, adding tests.
- BacktestingBrokerage will not create unnecessary order events
- Add `BaseData.Reader` implementation which consumes the `StreamReader`
directly, avoiding in between substrings and parsing improving
performance and reducing resource consumption
- Adding unit tests, including performance unit test showing a >50%
improvement
