[Coco] CoCoSDC and Extended ADOS3

Hmm.. my rom flasher is just a written wrapper around Darren's SDC.  It
loads a flat ROM image (not a bin file) into memory and proceeds to run the
sdcdos flasher.   Not sure why it would fail.  Maybe a BASIC guru should
look at my work.  it's mostly cheesy BASIC and a very simple asm helper.
And it has worked for me over and over with no weirdness. :(  I dont know
much about ADOS, other than a childhood friend raved about it, and Art
seems like a more than competent programmer.
