[AppStream] AppStream Generator 0.7.3 released!

[Matthias Klumpp]

Hi!
Another appstream-generator release, containing primarily random bugfixes.
When using asgen, please ensure that you compiled it with at least
version 0.8.0-alpha.6 of the dlang containers library. Previous
versions were affected by a bug leading to very hard to debug crashes.
See https://github.com/dlang-community/containers/pull/107 for more
information on that issue.
