Allow lnprob to return extra info about emcee

[dfm]

I love this idea and I do find that I need something like this a lot of the time! No promises for when this will be ready because I'm not giving this codebase the love it needs these days but it shouldn't be too hard to add.

Thanks for the suggestion!

I finally got around to implementing this. It's in the meta branch and there's an example here:

https://github.com/dfm/emcee/blob/meta/examples/blobs.py

It would be awesome if anyone who's interested wants to give this a try and let me know how it goes.

Awesome, I'll take a look at it, thanks.

Hmm... It doesn't seem to be working with multiprocessing right at the moment... let me track that down.

It actually looks like there was a different bug with how I was dealing with lnprobfns that didn't return blobs. It seems to be fixed now.

Done.
