Upgrade to libvips v8.13.0-rc1 (#3230)

* 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.
