remove the previous implementation of MSPA in the dashboard

[12rambau]

Now that the GWB module is set in the dashboard, @vogtpet suggested that we remove the previous implementation of mspa analysis.

• The Python implementation fragmentation map: https://github.com/openforis/mspa-analysis
• The R implementation Fragmentation map (R): https://github.com/openforis/sepal_mspa

@lecrabe do we have worflows that would force us to keep them ? (I would say no for the Python one but I don't know for R)

Can @lecrabe confirm that these two modules can be removed from test and prod?

@cdanielw & @12rambau yes confirmed, the GWB module covers already the functionalities in those initial modules. They can stay on the github repository for posterity.
