Docker image for OCR and OpenCV service with Python3 on Heroku

This docker image is based on heroku:16 stack and has Python3, OpenCV and Tesseract features for Heroku. Tesseract will be updated to v.4 when stable.

Versions

• Python3: 3.6.2
• OpenCV: 3.3.1
• Tesseract: 3.05.01
• Tessdata: 3.05.01
• Leptonica: 1.74.4

Forked from

• [supistar/docker-heroku-python3-opencv-tesseract]

I fixed some stuff that didn't work for me, switched to a newer Heroku stack and updated all the packages above to the latest versions.
