Simplify updating the exif tags dump file

[EtiennePelletier]

This PR addresses the issue where adding images to the repository without updating the dump file breaks the tests for exifread.

Key Changes:

• Added a Makefile to replicate the tests for exifread, as inspired from the CI workflow. Improved flexibility for various extensions and file names.
• In case EXIF.py isn't locally installed (e.g., for contributors who don't develop exifread), I opted to leverage uv to fetch the latest published version of exifread and run it in a virtual environment.
• Updated the dump file by including the necessary fixes from PR #173 and PR #196 due to issues with HEIF files in the latest version of exifread.

Please see the related PR #202 that mirrors the changes to correctly find all image files in the exifread repository.

I welcome any feedback or suggestions on these changes!
