Detect text-reuse with Python version of Passim and compare

[piconti]

Once the full text-reuse clusters have been generated and all works as intended with passim v1, it would be interesting to also perform this detection with the new python version v2, because:

• Python version v2 is more recent and currently being maintained, while v1 is old and not maintained anymore
• Staying on python instead of having various new dependencies with java, spark, scala etc is simpler in terms of the project's sustainability
• The python version does not require the first step of boilerplate detection, which could mean a much faster process.

Hence, based on the results, it might be relevant and useful to switch to the python version in the mid-long-term.

The action points are:

• Recompute the text-reuse with the updated version
• Compute statistics & visualizations to compare the results with the old version computed on new data
• Optionally change the approach for future text-reuse processings and/or look into how to match the scala performance with the python version
• Document process when using the python version
