## usage
```ts
import { assertEquals } from "https://deno.land/[email protected]/testing/asserts.ts";
import { Buffer } from "https://deno.land/[email protected]/node/buffer.ts";
import crc32 from "https://deno.land/x/buffer_crc32/mod.ts";
Deno.test("crc32", function() {
const input = Buffer.from('hey sup bros');
const expected = Buffer.from([0x47, 0xfa, 0x55, 0x70]);
assertEquals(crc32(input), expected);
});
