Add RData and RData.gz formats

[hexylena]

RData has a wide array of formats, some more useful than others. There's the binary RData format which can optionally be gzipped. Then there's an ascii version of that which only holds a single variable (which we ignore).

Can you stick a file_ext = 'rdata' on the implementation class?

Also - I don't think Galaxy is really going to like have two implementation of the same short extension - is that intentional? If yes, can you just have one class represent both "flavors" or RData - maybe storing whether it is compressed or not as a metadata element. If no, can you give them different extensions on the class and when registering them with Binary.

@jmchilton, sure, those all sound like good suggestions!

@jmchilton okay, just merged them into one datatype. I mostly added the second "just because". They're do the same thing, and library reading one will read the other, so I didn't bother with metadata elements either.

Awesome - thanks. 👍
