Roman Artiukhin b8238f7b20 imageviewer: Initial support for JPEG progressive images. Add decoder
Added jpeg decoder jpegp.c using RAINBOW lib. Currently enabled only for pictures not supported by old decoder (as old decoder more optimized for low mem targets)

Someone TODO:
 * Old decoder has optimized downscale logic which new decoder doesn't have (it gives big difference in required memory and time for decoding). This logic should be ported/adapted if possible.

 * Add smooth downscaling.

 * Grayscale support
