Description

This PR integrates OME Arrow and adds a new to_ome_parquet method which allows the export of image and feature data within Parquet files. CytoDataFrame can automatically read OME Parquet files and display images which are in OME Arrow format.

Additionally I fixed a bug which @jenna-tomkinson mentioned that prevents additional displays of CytoDataFrames within Jupyter notebooks (after the first).

What kind of change(s) are included?

  • Documentation (changes docs or other related content)
  • Bug fix (fixes an issue).
  • Enhancement (adds functionality).
  • Breaking change (these changes would cause existing functionality to not work as expected).
