Bug#955764: librust-cargo-dev: dependencies unsatisfiable

[peter green]

Package: librust-cargo-dev
Version: 0.41.0-2
Severity: serious
Tags: fixed-upstream

librust-cargo-dev depends on librust-humantime-1+default-dev but rust-humantime 
in debian is now at version 2.0.0. This seems to have been fixed upstream.
