adding dependencies for sci-wms

I'm trying to build sci-wms as a conda module, and here are the dependencies.   I haven't got sci-wms working yet, but I'm very close
@rsignell-usgs I believe that you have a reason for using @kwilcox fork instead of the main repo,

https://github.com/asascience-open/sci-wms.git

It would be nice to have a comment there for future reference.
