libwebp / cwebp binary
-----------------------

This package bundles the official cwebp command line tool from the libwebp
project (https://chromium.googlesource.com/webm/libwebp) in order to provide
offline WebP encoding on macOS. The executable is included without
modification apart from being combined into a universal (arm64 + x86_64)
binary and ad-hoc signed for development builds.
