• Updated handling of non-numeric house numbers
• Updated naming of files saved to the artifacts folder

**Updates & Enhancements:**
• Improved accuracy & expanded coverage of the geocoder
• Added functionalities allowing for model training based on custom target classes
• Extended the set of standard target classes
• Improved handling of user-defined block group and census tract GEOIDs
• Added GeoLookUpLooper() class which allows for easier building of geolookup tables

**Updates & Enhancements**:

- Improved & reduced memory usage
- Updated documentation including more clear docstrings , error messages, and progress messages
- Updated validators by reducing extensive checks, correcting null calculations, and including more flexibility
- Improved & reduced ZRP() runtime
- Updated documentation including more clear docstrings , error messages, and progress messages
- Provide more robust errors
- Extend race & ethnicity proxying options. Now ZRP name + geo, BISG name + geo, name-only, and geo-only proxies can be generated using ZRP() and its subclasses
- Updated BISG generation to normalize the data
- Include more robust support file checks to provide early indicator if supporting files have not been downloaded from GitHub
- Additional pre-proxy generation data processing to support customization

This release contains a few bugs fixes. Some highlights include:

* Enable windows installation without error
* Fiona, a package used for reading geospatial data, has requirement files that are more complex to install on Windows systems.
* We isolate code using Fiona in a separate document
* We provide unique installation instructions for [Unix-like](https://github.com/zestai/zrp#unix-like-systems) and [Windows](https://github.com/zestai/zrp#windows) systems
* Updating parallel processing default to -1
