Disable exporting range-v3 dependency

[sjahr]

Right now, the range-v3 dependency causes errors when a project depends on fp and range-v3 like this:

--- stderr: core

Failed   <<< core [1.93s, exited with code 1]

The error seems to be caused by range-v3 itself so I think it might be good to temporarily disable exporting the range-v3 dependency until the issue is resolved upstream
