Pure Rust implementation of the [Grøstl] cryptographic hash function.

## Examples

```rust
use groestl::{Digest, Groestl256};
use hex_literal::hex;

let mut hasher = Groestl256::default();
hasher.update(b"my message");
let hash = hasher.finalize();

assert_eq!(hash, hex!("dc0283ca481efa76b7c19dd5a0b763dff0e867451bd9488a9c59f6c8b8047a86"));
```
