@brief Main entry point for the reference decoder
The program takes two arguments: the pathname to the file that contains a
sample to decode and the pathname to the output file for the decoded image.
The input file should contain a single encoded sample without any header.
The output file can be a DPX file, otherwise the decoded image is written to the output
file without a header.
The image is decoded to the same dimensions as the encoded image and the decoded format
is the same format as the original source image input to the encoder.
