Chromaprint: download ældre versioner

- Fixed a heap buffer overflow when decoding a fingerprint that has extra data after the encoded values. Applications that decode fingerprints from untrusted sources should update.
- Fixed building against FFmpeg 4.x, which had not compiled since the channel layout API changed in 5.1
- Audio can now be fed in buffers that do not end on a frame boundary; previously a partial frame at the end of a call was dropped
- Fixed an implicit integer conversion warning on LLVM
- Fixed installing to absolute paths
- Build fpcalc against the system FFmpeg in CI

- Added support for FFmpeg 8.0
- Added chromaprint_decode_fingerprint_header function
- Added missing chromaprint_get_algorithm function implementation
- Optimized simhash calculation and fingerprint decoding
- Improved fingerprint compression performance by pre-allocating vector storage
- CMake improvements: updated minimum version to 3.10, use GNUInstallDirs, install config targets
- Build Linux ARM64 binaries
- Allow build to exclude internal avresample

- No functional source code changes.
- Fixed some compiler warnings.
- Rebuilt the fpcalc binaries with FFmpeg 4.4.1.
- Added support for fat binaries on macOS, with support for both Intel and Apple silicon.
