		const hash = new SHAKE(128);

		hash.update('foo');
		hash.digest({ buffer: Buffer.alloc(2048), format: 'hex' });

		hash.update('we can keep reading data even after digesting');
		#### `#digest([options={}])`

		hash.digest();
		// => hash of everything so far as a Buffer object
		Digests the hash and returns the result. After calling this function, the hash may continue to receive input.

		Options include:

		* `buffer` (Buffer): Optional. A pre-allocated buffer to fill with output bytes. This is how XOF algorithms like SHAKE can be used to obtain an arbitrary number of hash bytes.
		* `format` (string): Optional. The encoding to use for the returned digest. Defaults to `'binary'`. If `buffer` is also provided, this value will passed directly into `Buffer#toString()` on the given buffer.
		* `padding` (byte): Optional. Override the padding used to pad the input bytes to the algorithm's block size. Typically this should be omitted, but may be required if building additional cryptographic algorithms on top of this library.

		If a `format` is provided and is a value other than `'binary'`, then this function returns a `string`.
		Otherwise, it returns a `Buffer`.

		##### Example

		```javascript
		const hash = new Keccak(256);

		hash.update('hello');

		hash.digest({ buffer: Buffer.alloc(32), format: 'hex' });
		// => hash of 'hello' as a hex-encoded string
