Font metadata support #54
Description
Context: https://gitlab.gnome.org/GNOME/gnome-font-viewer/-/merge_requests/49#note_1784619
we're not doing much other than displaying fonts, reading their metadata, and installing them
Hm, yeah, crossfont doesn't support that, but given that it's a thin wrapper over systems API it might be easy to add.
it's similar to what font-kit was aimed to be.
