Inserting the coregistration step
Following [#70]
From what I saw of the iota² worflow (correct me if I have wrong), the coregistration step should be inserted between the 2nd (generate common masks) and the 3rd step (compute validity mask by tile).
Like this all the sensor data are already reprojected in the same epsg, and the bands are stacked per day.
I don't know if it's has to be a particular step or if it can be add to the 2nd step (and only triggered if the config file contains a VHR argument), what do you think about ?
