Shift in s1tiling outputs

We use s1tiling with develop branch at commit e14776bc and otb binaries 8.1.2 for ubuntu.

We use the output of s1tiling to detect water in serveral areas and have a reference database which is accurate.

The s1tiling outputs seem to be shifted according to the ASC or DES orbit (tile s2 20QPB) :

DES 20210222 ASC 20210224

This shift in the image is penalizing because our reference data used to train a machine learning model no longer corresponds to the water

We did not notice this issue with OTB 7.4 and s1tiling 0.3.0rc2 in previous run.
