astrophysical categories are now BNS, NSBH, BBH. Templates greater
that 3 solar mass are considered BHs. Previous mean mass-gap counts
are distributed equally between BBH and NSBH mean counts.

- em-bright source code is moved to its own repository
- remove all docs and test
- update dependencies

Fix the following deprecation warning:

    H5pyDeprecationWarning: The default file mode will change to 'r'
    (read-only) in h5py 3.0. To suppress this warning, pass the mode
    you need to h5py.File(), or set the global default
    h5.get_config().default_file_mode, or set the environment
    variable H5PY_DEFAULT_READONLY=1. Available modes are: 'r', 'r+',
    'w', 'w-'/'x', 'a'. See the docs for details.

Speed up imports by up to a second by replacing uses of `pkg_resources`
with the new Python standard library module `importlib.resources` (or,
for Python < 3.7, the backport `importlib_resources`). The old
`pkg_resources` module is known to be slow because it does a lot of
work on startup.

See, for example,
[pypa/setuptools#926](https://github.com/pypa/setuptools/issues/926) and
[pypa/setuptools#510](https://github.com/pypa/setuptools/issues/510).
