switch to python-package-template
this MR migrates the package to use the python-package-template
template via cruft.
see https://codebase.helmholtz.cloud/hcdc/software-templates/python-package-template
this involves a migration to the reuse
library which is why a lot of copyright-statements and license stuff has been changed.
in short:
- everything under
docs/
is now licensed underCC-BY-4.0
with copyright by GFZ and Hereon - everything under
demessaging/
got copyright headers for GFZ, HZG and Hereon
ping @nils-brinckmann
this migration has been discussed (via mail) with Martin Hammitzsch and Christian Meeßen from GFZ
