conda environment files are inconsistent and incomplete

[bsmoliak]

Describe the bug

The conda environment files available in the repository are inconsistent across the platforms (linux, macOS) and incomplete in some cases. A particular issue appears with the ingest environment.

To Reproduce

Steps to reproduce the behavior:

1. Open notebook associated with an environment file.
2. Run all cells.
3. See errors.

Expected behavior

No errors occur when running all notebooks on both linux and macOS.

Additional context

Eventually it would be nice to leverage GitHub Actions to automatically check the environment files and notebooks.
