FROM fred2/optitype:latest

The purpose of this container is only to add tools and configuration settings needed to run our custom optitype prep script, so all optitype related setup is pulled from the official container repository. However, tags are not kept up-to-date there; the most recent is tagged latest, but even that is missing a few new commits according to github. Should we move away from simply pulling from that repo, or should we keep it and just lock down our own version hosted on docker hub?

Note that because of the uncertainty, I've versioned our image as v 1.0.0 for now- if we decide to continue following the official repos, we can update it to 1.3.2 (most recent github release) or 1.3.0 (most recent non-latest dockerhub tag)
