tests/scripts/download-test-fonts.sh rewrite in Python3
Replaces download-test-fonts.sh with download-test-fonts.py which does the same work, and also avoids downloading anything if the files are already installed with the right content. Now uses the first 8 byte of each file's sha256 hash for the digest.
