Pull request overview

This PR updates download_data() to fetch datasets via a pinned GitHub raw-content URL derived from an index “path” field (instead of consuming full external URLs directly), aligning data access with a more controlled/pinned resource layout.

Changes:

• Switched dataset index records from url to path, and added URL construction helpers (_build_data_url, _record_path).
• Updated download_data() to build the download URL from the record path and derive filenames from the record path suffix.
• Updated unit tests to reflect the new index schema and URL construction behavior.

File	Description
src/easydiffraction/utils/utils.py	Builds dataset URLs from a repo/ref/root + record path; updates download_data() accordingly.
tests/unit/easydiffraction/utils/test_utils_coverage.py	Updates mocked dataset index records to use path instead of url.
tests/unit/easydiffraction/test___init__.py	Updates lazy-function test to assert download_data() calls pooch.retrieve with the constructed URL.
