Docker pulls scraper

DockerHub provides an API endpoint to track the number of pulls of the images it hosts but no history. This small program allows to get that count and updates a .csv file to keep a record. It generates one .csv file per image, with the columns: Date, Count. Up to you to run the script every X times to add a new line in the files.
