Handle smile, keystone and fringe patterns provided by the ground segment.
The ground segment will provide smile, keystone and fringe patterns. They will be freely available but are not included in the L1B data. EnPT may implement appropriate correction algorithms but should at least add some information about these patterns in the L2A metadata.
Steps to do:
- download these patterns during EnPT runtime or include them in the repository
- handle them somehow (correction / additional L2A metadata)
