Detects whether a terminal supports color, and gives details about that
support. It takes into account the `NO_COLOR` environment variable.
This crate is a Rust port of [@sindresorhus](https://github.com/sindresorhus)'
[NPM package by the same name](https://npm.im/supports-color).
## Example
```rust
use supports_color::Stream;

if support.has_16m {
println!("16 million (RGB) colors are supported");
} else if support.has_256 {
