import fails without h5py

[mileslucas]

As noted in nespinoza/juliet#53 radvel doesn't install h5py within setup.py 117d4e6

This means a clean install (from inside a docker container)

$ pip install radvel

will fail to import

>>> import radvel
[...]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.7/site-packages/radvel/__init__.py", line 16, in <module>
    from .mcmc import *
  File "/usr/local/lib/python3.7/site-packages/radvel/mcmc.py", line 12, in <module>
    import h5py
ModuleNotFoundError: No module named 'h5py'

If h5py is pip installed, too, import works fine.

This had to be temporarily removed due to a build problem on ReadTheDocs. They can't install h5py and can't build the docs without it. Once they fix that issue then I'll add it back into the requirements, but for now your solution to install separately is the best we can do. If this is not fixed within a week or two I'll add a note to the install documentation.

Seems totally reasonable and understandable; thanks for the quick response.
