Corrected argument-forwarding error; set up job for porto data; split off ecotaxa TSV generation into its own module

Implemented check for multiple connected objects in mask frame, and optional restriction to the largest-area one; inference on autogenerated model now works with 100% accuracy when passing on training data

Lifted z-stack assertion, made util.loop_workflow more generic e.g. for on-the-fly data conversion tasks

Maintain DataFrame index throughout workflow, export patch filenames and complete source filepaths to workflow DataFrame; prepopulate patch UUID
