Add conditional code to handle workaround for sparse tables

[folmos-at-orange]

Description

When solving the issue #42 we had to make a workaround for writing sparse tables with empty lines. The bug requiring the workaround will be fixed in a upcoming Khiops version (https://github.com/KhiopsML/khiops/issues/235). When that lands we should have a conditional code on the khiops version to whether apply or not the workaround. This is to support all 10.x.x series.

Questions/Ideas

• Since is a critical part of the code we should be able to plug the function that writes a sparse row instead of testing the version for each row.
• In stand-by until the fix for khiops-core lands.

Note that it has been decided that khiops-python 11 will support only Khiops 11. So the issue is now to change the code for the upcoming version 11.
