ext: dsent: adds a Python interface, drops C++ one

This patch extensively modifies DSENT so that it can be accessed using Python.
To access the Python interface, DSENT needs to compiled as a shared library.
For this purpose a CMakeLists.txt file has been added.  Some of the code that
is not required is being removed.
