- Add YODA-py3-compatibility-for-IO_pyx.patch -- Py3 compatibilty
for IO.pyx; patch taken from upstream commit and modified to fix
further similar errors
(https://gitlab.com/hepcedar/yoda/issues/4).
- Change hashbangs referring to python or `env python` to use
`/usr/bin/python3` consistently in source dir, rather than
from buildroot after installation. This allows to run the tests
correctly in the %check section.
- Move binaries using the python module to python3-%{name}
package.
- Run make check.

- Switch to python3:
* Requires and BuildRequires switched to python3 versions
* Rename python package to python3-%{name} and provide
python-%{name} from it; this makes the py3 switch clear to
users.
* Explicitly pass PYTHON_VERSION as py3 version to make it build
against python3
* Drop an unecessary hashbang from a file in non-exec location.
- Remove an sed hack for buildroot in *.pyc file(s); no longer
needed.

- Update to version 1.8.0:
* Add extra optional bool arguments to the mkScatter converter
functions for Histo1D and Histo2D types.
* Force rebuild of the Python interface if a sufficient Cython
is found, even if the generated .cpp file is present at
configure-time.
* Final conversion to use ast module not just in autotype but as
