WIP: fixed python 2 version not being deployed to pypi (#6)

* WIP: Added type hints, still waiting on resolution of [so issue](https://stackoverflow.com/q/54425358/4200103).

* Added nox, updated travis.yml

* Added script to remove type-hints for all python versions below 3.6

* forgot to add test-requirements.txt

* removed 2.6 support

* - moved testing for different python versions from travis to nox
- added auto stripping of type hints

* decided to keep support for 2.6 until we need a lib that does not support it

* forgot to delete something from travis.yml

* fixed travis.yml for name of pytests method inside nox file

* moved type hints to .pyi stubs on deploy to prevent python version compatibility issues

* added deployment for other python versions
