Add script to set the physical sizes post import about idr0042-nirschl-wsideeplearning HOT 1 OPEN

Briefly investigated yesterday, my initial hope was to get this achieve this tasks using the basic CLI command i.e.:

• omero hql to retrieve the list of images
• omero obj update Image:xxx physicalSizeX=yyy to set the property

Unfortunately, the last part fails due to the fact physical sizes are Length object and this is not supported by the obj update subcommand as discussed with @joshmoore.
This might require a Python script using the API although @dominikl was considering whether this could be turned into a mini CLI plugin.
