Version 0.12.0 in pip is incorrect

The library that is installed from pip does not seem to contain the correct code from the 0.12.0 release. At least when I installed it, the `_build_get_range_request` function did not set the limit and so all my queries were failing because the response was too large.

Once I cloned the repo and ran python3 setup.py install from the source code, things started working as expected.
