Adjust dependency to support termcolor 1.2

The [1.2.0 update] to [termcolor] is backward compatible with the 1.1
versions. This adjusts the version specification for the dependency in
Cargo.toml to allow any version greater than or equal to 1.1 and less
than 2.0.

[1.2.0 update]: BurntSushi/termcolor@1.1.3...1.2.0
