Adds Betamax training files and a new switch between VHS and Betamax formats #59

HI Ali

The switch is probably a bit dirty, but it seems to work, and it makes it easy to add other formats. The Betamax training files work considerably better than using the VHS ones on a Beta source, and the results are better than V1.

Cheers

Jason

Looks good. Just one big thing: you don't need to duplicate the debruijn data - this is the training pattern that gets recorded to tape so it should be the same for every format. As a result I suspect that this breaks the training generator. And one small thing: I'd prefer subdirectories ie data/vhs instead of data-vhs. I'm happy to tidy this up and commit though.
