Main changes in this release:

- Better "neutral values" are returned: see https://github.com/dianna-ai/distance_explainer/commit/12a0d03250e0b17b066f5d47e20058833f0bac31 and https://github.com/dianna-ai/distance_explainer/commit/39433b5d7a19b9d6ca710ecc42fa89e6370b242c
- Add lower limit for DIANNA >= 1.4, which introduced a backwards incompatible change to a masking function that we use.
- Some type hinting:
- Dropped Python 3.8 support to use tuple builtin types
- Initial numpy NDArray hinting
- CI: added a PyPI release workflow
- Various minor fixes and clean-up
