Speckle Spatial filtering processing
Implement spatial speckle filtering with OTBDespeckle application.
Provide an optional spatial despeckling after concatenation.
Typical option evolution
[Filtering] filter_type = None/Lee/Frost/Gammamap/Kuan keep_non_filtered_data = True/False rad = ... # for all nblooks = ... # for lee, gammamap & kuan deramp = ... # for frost
In case no masking is done and the calibrated image isn't required (need an option), this extra processing could be chained in memory.
