M65: Provide assistive help messages for Windows users wanting to use '-b' to upload bitstreams

[gurcei]

There's a bit of rigmarole involved for Windows users to get bitstreams uploaded to their devices via the '-b' argument.

So if they attempt to, and it fails, I'd like to point them to a page with information on the preparatory steps, most of which I've outlined here (but perhaps it could have a better home somewhere else too):
