Notes:
this is generated from an excel sheet and actual ratios are hand picked to
spread out the ratios evenly to avoid having super-finely defined buckets
Too many buckets means more "runt" steps with repeated images to fill batch than necessary
ex. we do not need both 1.0:1 and 1.125:1, they're almost identical ratios
Try to keep around <20 ratio buckets per resolution, should be plenty coverage everything between 1:1 and 4:1
More finely defined buckets will reduce cropping at the expense of more runt steps
