[PATCH v2 13/18] spdx.py: Add test for version extraction patterns

[Stefano Tondo <stondo@gmail.com>]

From: Stefano Tondo <stefano.tondo.ext@siemens.com>

Add test verifying that version extraction patterns work correctly for:
- Rust crates (.crate files)
- Go modules
- Python packages (PyPI)
- Generic tarball formats
- Git revision hashes

Test builds tar recipe and validates that all packages have proper
version strings extracted from their filenames.
