packaging Julia packages for conda-forge

[ngam]

My second concern is that it is not completely clear to me to what degree this PR really addresses the issues it closes. For example, #14 is about packaging Julia packages for conda-forge, i.e. how should I create the conda-forge feedstock julia-rainfarm from https://github.com/jhardenberg/RainFARM.jl. While sorting out the depot paths certainly helps and might be necessary, from reading this PR I still don't know how to do this or where to look up the documentation. In terms of documentation, at a minimum I would expect a bullet point in the enumeration for new packages.

This is probably beyond the scope of this PR, but in that case we might want to keep #14 open for now.
