/**
* Returns `true` if the prefix array appears at the start of the source array,
* `false` otherwise.
*
* The complexity of this function is `O(prefix.length)`.
*
* @param source Source array to check.
* @param prefix Prefix array to check for.
* @returns `true` if the prefix array appears at the start of the source array,
* `false` otherwise.
*
* @example Basic usage
* ```ts
* import { startsWith } from "@std/bytes/starts-with";
* import { assertEquals } from "@std/assert";
*
* const source = new Uint8Array([0, 1, 2, 1, 2, 1, 2, 3]);
* const prefix = new Uint8Array([0, 1, 2]);
*
* assertEquals(startsWith(source, prefix), true);
* ```
