uscan: git repo without releases/tags

[Felix Natter <fnatter@gmx.net>]

hi debian-java,

I am starting to package libiconloader-java but unfortunately, there
are no releases or tags in the respository:
  https://github.com/bulenkov/iconloader

I kindly asked for a release, but the author does not respond for weeks
now.

How can I deal with this? Shall I write a debian/rules target
'get-orig-source' that clones the repo and creates a .tar.gz
from that (duplicating the Files-Excluded: mechanism)?

Is the upstream version 0.0+20191003 ok?

Thanks and Best Regards,
