- Add new library to do tiff import/export. This library is different from imageio in that it doesn't pull in additional 3p libraries. This reduces binary size and reduces complexity in maintaining the android build (which depends on libs/viewer). - The encode() code has been moved from libs/viewer to libs/imageio-lite - encode/decode only handles the simplest case of uncompressed rgba.
