 * Class Tiny_AS3CF

 * Known issues with integration:
 * - When as3cf removes local files, Tinify can't do compression on files that are
 *   already offloaded. Possible solutions are to download the remote file, compress
 *   We can use `tiny_image_after_compression` to possible remove the file after
 *   compression is done. A lot of functonality for Tinify is based on having the
