Pure Rust implementation of the `bash-prg-hash` function specified in [STB 34.101.77-2020].
## Examples
```rust
use hex_literal::hex;
use bash_prg_hash::{BashPrgHash2561, Digest};
use digest::{Update, ExtendableOutput};
let mut hasher = BashPrgHash2561::default();
hasher.update(b"hello world!");
let mut hash = [0u8; 32];
hasher.finalize_xof_into(&mut hash);
assert_eq!(hash, hex!("0C6B82907AE77386DDF0BA2D7CFDDD99F79A9B0094E545AEF8968A99440F5185"));
```
