Some logo proposals for the Debian R Packages Maintainers team.

The Debian swirl logo is licensed under CC-BY-SA 3.0 or LGPL-3+ whereas the R logo is licensed under CC-BY-SA 4.0 or GPL-2. Both seems to be legally compatible which allows us to merge them. So, let's try to be an artist. Some tests where the grey circle of the R logo is replaced by the Debian swirl.
