Extract u-boot multi-file image in Python

This simple piece of code shows how to extract/decompress a u-boot multi-file image created with mkimage using Python. The image format is very simple:

64 bytes of image header.
4 bytes for the size of first image.
4 bytes for the size of second image.
4 bytes of zeros for termination.

You need to remember also that each image is padded to 4 bytes.
