minor pybigtools complaints

[sergpolly]

pybigtools can feels a bit alien as a python module
would be nice to have access to things like __version__, __path__ etc etc - e.g. import pybigtools as pybig; print(pybig.__version__)

[ghuls]

__path__ is already there:

__version__ will be there if: #32 gets merged.

In [1]: import pybigtools as pybig

In [2]: print(pybig.__version__)
0.1.4-dev

In [3]: print(pybig.__path__)
['/anaconda3/envs/pybigtools/lib/python3.10/site-packages/pybigtools']
