*/ Changelog:
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?
