Simple way to use [`include_bytes!`](https://doc.rust-lang.org/std/macro.include_bytes.html) for directories.

# Example 

You can embed files two ways.

## Bytes mode

```rust
use dir_embed::Embed;

#[derive(Embed)]
#[dir = "../web/static"] // Path is relativ to the current file
#[mode = "bytes"] // Is the default. Can be omitted.
pub struct Assets;

fn main(){
    let file: &[u8] = Assets::get("css/style.css").expect("Can't find file");

    let string = str::from_utf8(file).expect("Failed to parse file");

    println!("{string}");
}
```

## Str mode

```rust
use dir_embed::Embed;

#[derive(Embed)]
#[dir = "../web/static"] // Path is relativ to the current file
#[mode = "str"]
pub struct Assets;

fn main(){
    let file: &str = Assets::get("css/style.css").expect("Can't find file");

    println!("{file}");
}
```
