* update the CMakeLists
- remove the deprecated commands ('PythonInterp', ...)
(https://cmake.org/cmake/help/latest/module/FindPythonInterp.html)
- change the CMake minimum version from 3.8 to 3.12 (released in July 2018)
* rename the libiec61850 Python module into 'pyiec61850'
- to avoid name conflict with the name for the C static lib
- the build artifacts are now 'pyiec61850.py' and '_pyiec61850.so'

1. Allow specifying Python interpreter version with BUILD_PYTHON_VERSION
2. Fix Python modules install path generation (would produce spurious
line feed which would cause destination directory to be
/usr/lib/python*/dist-packages\n -- note the final \n!
