- add --vips-config flag to show configuration info
- add "bitdepth" param to tiff load and save, deprecate "squash" [MathemanFlo]
- tiff load and save now supports 2 and 4 bit data [MathemanFlo]
- ppmsave also uses "bitdepth" now, for consistency
24/4/20 started 8.9.3
- better iiif tile naming [IllyaMoskvin]
