Publish images for branchwater components

[luizirber]

After #4 is merged tag a new release and start publishing images, to make it easier to external projects to bring up/expand on branchwater

Questions:

• where to host? dockerhub, quay.io, ghcr.io?

That's great!

In my experience, https://hub.docker.com is good. If you need help, we have some GitHub Actions to automatically prepare and push a Docker image to DockerHub. It's relatively simple, most times we install a tool via (bio)conda in the container and then have an Git Hub action that builds everything and connects to DockerHub via GitHub Secrets. At least I could provide some example code, if needed.
