+ Changelog:
+ v2.3 - allow jffs by adding its magic number (0x8519)
+ added parameter option -i to ignore unknown magic numbers
+ v2.2 - fixed checksum byte calculation for other versions than 0x2019
+ fixed rare problem with padsize
+ updated info to stock firmware 2.00.20
+ fixed typos
+ v2.1 - used "wrt350n.bin" for the created image (closer to stock)
+ added option to create the image in two separate steps (-b / -z)
+ v2.0 - complete re-write
-// ToDo:
-// * Has NODE to be added to bin file *after* creating checksum byte?
