# then manually copying extensions, keeping them in order
# An alternative would be using https://github.com/ome/bioformats/blob/19d7fb9cbfdc1/components/formats-api/src/loci/formats/readers.txt
# Or, https://bio-formats.readthedocs.io/en/latest/supported-formats.html
# For file extensions with multiple dots, here only last part is recorded
# Video, compression formats and duplicates excluded
# https://github.com/ome/bioformats/blob/19d7fb9cbfdc1/components/formats-api/src/loci/formats/readers.txt
# External readers listed on that webpage need to be excluded
# All the rest needs to be included
