add a dockerfile to build the sciClone package

[shenkers]

Hi @chrisamiller ,

I'm doing a volunteer project with a PI and wanted to run sciClone on the dataset. I saw that you had install instructions, but thought it might be nice for future visitors if there was a docker image. I guess ideally someone like biocontainers could host it so users don't have to build it, but thought even having the Dockerfile would make it easier for people to use.

Let me know if you have any feedback on the change.

Best,
Sol

update: it looks like the image doesn't work as is, I think because it runs in R v4, and something about how data-frame slicing by column index changed ( df[,1] used to return a vector, but now returns a 1-column data.frame? ). It looks like there are a lot of places that this sort of slicing is used, so it probably makes sense to use an R environment that mimics the original setup. I was browsing the issues and saw your reference to seqfu/sciclone docker image, it looks like theirs uses R 3.6.3 and BioConductor 3.10.
