* Switch from decompress-zip to extract-zip The former seems to hang when unzipping a ZIP64 file that uses the general purpose bit flag 3 as file entry. See: https://github.com/thejoshwolfe/yauzl#no-streaming-unzip-api * Prefer to call via static member instead Makes it clearer that a static method is being called. * `flatten-orange.jpg`: save without chroma subsampling To ensure no down-scaling of the Cr/Cb channels.
