Freecom MusicPal #2

Since the link to the mpimage tool referred to by the wiki page Freecom's MusicPal Firmware in the Firmware Tools section is broken, and I haven't been able to find it on the net, I've decided to code my own.

I've just pushed the initial version which displays the firmware header in a github repository named mp-utils.

Example:

$ mpimg mpimage.bin

Firmware file size : 6801772 bytes

FIELD           VALUE

-------------------------------------

MAGIC           adma1.01

CRC32           0xE268FD23

VERSION         1.67

NAME            MusicPal Version 1.67
