LosslessCrop method

Performs a lossless crop on the specified JPEG file. To perform this lossless operation the width and height of the cropped rectangle must be adjusted so that the image dimensions are a multiple of the iMCU size (usually 8 or 16 pixels). Therefore the output width or height can be slightly greater than the requested image size.
