dub / use git branch

[Robert M. Münch]

I want to use a specific branch version if a package. I specified the 
branch version in a dub.selections.json file.

But it seems that dub requires a ZIP file that can be downloaded from 
code.dlang.org, which of course fails because the branch is only 
available on github.

Fetching rtree ~fix-#3 (getting selected version)...
Downloading https://code.dlang.org/packages/rtree/~fix-#3.zip failed 
with 404 (Not Found).

How am I supposed to switch to a branch version of a package to try a 
bug-fix version for example?
