Uses image + rayon to make a quick and easy batch image sequence reencoder. Every one I found was slow and I didn't need a UI, so this.
Pass path of directory containing image sequence (of .tiffs for example) and extension to convert to.
climvert ~/Pictures/input_img png
Note: exclude trailing / to place in dir next to original, include to place inside original dir.
Can recode ~1000 tiff to png in ~30sec
