BEGINRELEASENOTES

Make the python bindings install prefix conform to python conventions by default and allow overriding with the EDM4HEP_PYTHON_INSTALLDIR cmake variable
- Default prefix is now <prefix>/lib[64]/pythonX.Y/site-packages (where lib or lib64 is defined from the platform defaults and X.Y is the python major and minor version).

ENDRELEASENOTES

Fixes #220

See https://github.com/AIDASoft/podio/pull/599 for some discussion on how we arrived at this solution.

The corresponding changes for spack are ready here. I will open a PR to upstream spack as soon as this is merged.
