Encode bitmap(bmp) file with run-length encoding(RLE), just like RLE4 and RLE8, but extend to RLE16,
RLE24 and RLE32.

Usually, this project will be used in GUI of embedded system, to make the image files smaller, and
save the IO bandwith. If the GUI support JPG or PNG, the compression ratio is much better than RLE,
but how about the embedded system encounters both caculate limitation and IO bandwidth limitation?
Try this project, I hope it can make a banlance between caculation and bandwidth.

But first of all, you should know that the compression ratio of RLE is highly depend on the bitmap
file data, the ratio can larger than 1, only when the same color continuously repeats in one line,
it will gain a smaller compression ratio.
