Parse environment variables by defining a struct.

### Example

```rust

use envopt::EnvOpt;

#[derive(EnvOpt)]

pub enum EnvOpts {

    #[envopt(name = "FOO")]

    Foo,

    #[envopt(name = "BAR", default = "default-bar")]

    Bar,

}

pub fn main() {

    EnvOpts::validate_or_exit();

    println!("FOO: {}", EnvOpts::Foo.value_or_exit());

    println!("BAR: {}", EnvOpts::Bar.value_or_exit());

}

```
