Install local incidence-mapper R packages during docker build?

[famulare]

@rnunez-IDM and I were wondering if we could install the local r packages during the docker image build. I'm thinking that if the issue is installing something from within the image itself, we can instead install from github with devtools::install_github(...). Thoughts on this? It's become an issue as we've got a new person working, and my old habit of keeping an image up for months isn't ideal. Thanks!

I am just circling back to images. I have some new lesson learned from other projects usign R docker containers. I will address this along with other issues in coming week
