Some of the packages that provide the core-dump-handler virtual package
(corekeeper, minicoredumper, systemd-coredump) reduce the size of the
core dump using compression (minicoredumper, systemd-coredump). The
systemd-coredump package uses zstd compression and minicoredumper can
be configured to use any compressor at all but the manual page lists
gzip bzip2 xz as examples. I think it would be good to detect,
decompress and process gzip bzip2 xz zstd files at minimum.
