## Usage

```rust
let dep = "requests[security, socks] <= 2.28.1, == 2.28.*; python_version > '3.7' and extra == 'http'";
let parsed = parse(dep).unwrap();
let expected = Dependency {
    name: "requests",
    extras: vec!["security", "socks"],
    spec: Some(Spec::Version(vec![
        VersionSpec {
            comparator: Comparator::Le,
            version: "2.28.1",
        },
        VersionSpec {
            comparator: Comparator::Eq,
            version: "2.28.*",
        },
    ])),
    marker: Some(Marker::And(
        Box::new(Marker::Operator(
            Variable::PythonVersion,
            Operator::Comparator(Comparator::Gt),
            Variable::String("3.7"),
        )),
        Box::new(Marker::Operator(
            Variable::Extra,
            Operator::Comparator(Comparator::Eq),
            Variable::String("http"),
        )),
    )),
};
assert_eq!(parsed, expected);
```
