Task completed: A DOS floppy archiver for Adafruit Floppsy. It copies floppies in any of the 4 standard DOS formats to the SD card, without requiring a PC to be connected.

This is for nice simple data floppies without any bad data. If you have commercial, copy-protected floppies or floppies with bad sectors, you'll still want to use greaseweazle or fluxengine to do the best possible job of archiving them.

The code is all open source, and could potentially be adapted to run with the Floppy Featherwing if someone is interested. (the floppsy board is still not ready for release)

Yes! My floppy emulator now successfully boots the Xerox 820 by emulating an FM-formatted 8" floppy disk drive!

The hardware is a prototype Adafruit Floppsy and the code is not online yet as my last "aha" moment about correct FM encoding probably broke MFM encoding and I didn't want to do that.

I'll get it cleaned up and pushed to that open pull request in Adafruit_Floppy tomorrow with any luck.

(Neither MFM nor FM emulation support writing, and I don't think implementing that's on the table right now, so this is still much less capable than a gotek with flashfloppy.. but I'm still excited about it)
