Pin OpenCV <= 3.4.9.31 for better Python distribution support. (#31)

* add opencv to required packages in setup.py

* align package dependencies with deepcell-toolbox

* pin opencv to last supporting 2.7 build.

* bump version to 0.2.6 and format with a constant VERSION variable.

* add opencv limit to install_requires.

* Test installation using setup.py instead of requirements.txt
