Get look direction parameter ready for NISAR

[garlic-os]

The look_dir parameter as provided in a YAML file is never used. It is accessed in one spot to validate that it is either "left" or "right", and never again. A vscode all files search for the term "look_dir" only produces results from inside other data structures and that one validation check, and none where the look_dir from a YAML run config gets used.

Do we not use Look Direction anymore, or is it being left out somewhere on accident?

Not all sensors have same look direction. Will defer to @jlmaurer if this was a placeholder for the future. E.g. NISAR/ CSK etc.

@dbekaert @garlic-os yes this will depend on the sensor. Right now everything is right-looking, but very soon we will have a left-looking sensor (NISAR). We may want to take a look at the workflow and make sure the look direction is properly carried through.
