Fix Exiftool not being able to get the metadata for compressed SWF files. Exiftool requires Compress::Zlib as an optional dependency to decompress compressed SWF files, but it wasn't in the Docker image. Archive::Zip is required for Zip files and Digest::MD5 for certain other metadata (see "DEPENDENCIES" in exiftool README).
