Unused import std::io::Write

[dtolnay]

I ran cargo install cargo-count on nightly. It worked but I saw this warning:

   Compiling cargo-count v0.2.1
.cargo/registry/src/github.com-1ecc6299db9ec823/cargo-count-0.2.1/src/main.rs:190:5: 190:19 warning: unused import, #[warn(unused_imports)] on by default
.cargo/registry/src/github.com-1ecc6299db9ec823/cargo-count-0.2.1/src/main.rs:190 use std::io::Write;
                                                                                      ^~~~~~~~~~~~~~

Ah thanks, yeah I need to remove it. I'll do this on the next PR unless someone puts one in first.
