/**
* Calculates the [Keccak256](https://en.wikipedia.org/wiki/SHA-3) hash of a {@link ox#Bytes.Bytes} or {@link ox#Hex.Hex} value.
*
* This function is a re-export of `keccak_256` from [`@noble/hashes`](https://github.com/paulmillr/noble-hashes), an audited & minimal JS hashing library.
*
* @example
* ```ts twoslash
* import { Hash } from 'ox'
*
* Hash.keccak256('0xdeadbeef')
* // @log: '0xd4fd4e189132273036449fc9e11198c739161b4c0116a9a2dccdfa1c492006f1'
* ```
*
* @example
* ### Calculate Hash of a String
*
* ```ts twoslash
* import { Hash, Hex } from 'ox'
*
* Hash.keccak256(Hex.fromString('hello world'))
* // @log: '0x3ea2f1d0abf3fc66cf29eebb70cbd4e7fe762ef8a09bcc06c8edf641230afec0'
* ```
*
* @example
* ### Configure Return Type
*
* ```ts twoslash
* import { Hash } from 'ox'
*
* Hash.keccak256('0xdeadbeef', { as: 'Bytes' })
* // @log: Uint8Array [...]
* ```
*
* @param value - {@link ox#Bytes.Bytes} or {@link ox#Hex.Hex} value.
* @param options - Options.
* @returns Keccak256 hash.
