planemo upload for repository https://github.com/lldelisle/tools-lldelisle/tree/master/tools/max_projections_stack_and_upload_omero commit 69a86e0a8ef82ce3c2232b99f72717a184f4d4cf

/**
 *
 * The purpose of this script is to combine a series of time-lapse images into
 * one file per image with possibly multiple channels and multiple time points
 *
 * To make the script run
 *  1. Create a parent folder (base_dir) and a output folder (output_dir)
 *  2. The struction of the base_dir must be: one directory per final image and per channel. All the directories should be: `unique_identifier` `suffix specific to channel`.
 *  3. The image names will be sorted before being merged.
 *  4. The images must be regular tif.
 *
 * The expected outputs are:
 *  1. In the output_dir one tiff per `unique_identifier` (potentially multi-T and potentially multi-C)
