v1.0.0

This release is a combination of major internal refactorings and some minor interface changes. Overall, you should expect your upgrade from pre-1.0 versions to be relatively painless. A big thank you to @genhernandez and @csb19815 for their valuable design feedback.

Here is a list of interface changes:

• The class partridge.gtfs.feed has been renamed to partridge.gtfs.Feed.
• The public interface for instantiating feeds is partridge.load_feed. This function replaces the previously undocumented function partridge.get_filtered_feed.
• A new function has been added for identifying the busiest week in a feed: partridge.read_busiest_date
• The public function partridge.get_representative_feed has been removed in favor of using partridge.read_busiest_date directly.
• The public function partridge.writers.extract_feed is now available via the top level module: partridge.extract_feed.

Miscellaneous minor changes:

• Character encoding detection is now done by the cchardet package instead of chardet. cchardet is faster, but may not always return the same result as chardet.
• Zip files are unpacked into a temporary directory instead of reading directly from the zip. These temporary directories are cleaned up when the feed is garbage collected or when the process exits.
• The code base is now annotated with type hints and the build runs mypy to verify the types.
• DataFrames are cached in a dictionary instead of the functools.lru_cache decorator.
• The partridge.extract_feed function now writes files concurrently to improve performance.
