Title: Minor update to optional dependency instructions

I've added h5py to the list of optional dependencies, and also tried to make it clearer that optional dependencies are *optional*. I came across a user the other day who thought they were *required* so that astropy would work, even if they were only for specific functionality. This is a pretty trivial PR, so I'll merge in a couple of days.
