This allows unpacking files that would otherwise not be recognised as of
a particular type, such as self-extracting files supported by zip, 7z or
cabextract.
Using g_load_contents () for the checksum computation uses a lot of memory
(for large files) and actually fails for files larger than 4 GiB. Instead,
this implementation uses GInputStream to read the file in small buffers
and feeds the GChecksum manually.

This will initialise a git repository with the archive's contents, to
allow us to apply git-formatted patches easily, allowing binary files
patching, file renaming, and all the advanced features offered by git
patches over plain patches.
* Add more checksum types for files and archives
Many upstreams don't use sha256, some use even stronger checksums like
sha512, and its nice to be able to use these. Some system uses
weaker checksums, which you can work around by recomputing your own,
but sometimes that is a bit painful, for example when you're
auto-generating flatpak-builder manifests based on some other format
such as npm lock files.
This adds all the checksum types that GChecksum supports in the
glib version we currently use: md5, sha1, sha256, sha512
