Pantab

- Implemented a new ``use_parquet`` keyword in ``frame_to_hyper`` which uses Parquet as an intermediate storage solution instead of pantab's own internal C library. This may provide a small performance boost at the cost of additional disk usage
- Fixed issue where pantab was not compatabile with Hyper versions 0.0.14567 and above. See the :ref:`compatability` documentation.

This is a bug fix release that fixes an issue where pantab would error when trying to read Non-nullable strings

- Fixes an issue where unsupported data types in Hyper Files would crash the Python process
- Adds support for reading DATE types
