v1.1.1 | Safer zip reader

Updates include

• Implemented context manager for zip reader, as suggested by #80 (reference)
• Re-released this v1.1.1 update from earlier in August because the source code still had v1.1.0 and thus did not actually match the github versioning. This would result in you getting a push to update to the latest version, even though this was the latest version.
  • Needed to delete the v1.1.1 release and the v1.1.1 tag, push the updated __init__.py, and re-release the tag.
  • Be sure to avoid this mistake yourself!
