Support Py3

This release update to support Python-3.

v1.0.1-alpha

Fix version number

v1.0-alpha

Running in Python 3.

Require Astropy < v4

EADA still relies on Python-2, and apparently Astropy-4 setup script is not properly handling old (Py2) necessary dependencies (e.g., future, configparser), which is reasonable. Since EADA does not use latest Astropy features, we are safe to hold back on prior versions.

Fix Specsearch multiple readings of same service data

This fix specsearch reading multiple times the same cached file when SSAP service table had multiple equally-named object (id column). That would cause suggest_dataset_basename() to offer the same value for each (equally named) result. Solution now defined the cachefile name after resource's accref.
