Description

The current tar file detection does not detect every tar file archive.

Steps to reproduce:

Download https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.7.12.tar.gz

gunzip linux-6.7.12.tar.gz

import { fileTypeFromFile } from 'file-type'

const result = await fileTypeFromFile("linux-6.7.12.tar");
console.log(JSON.stringify(result));

Outputs

undefined

This issue seems to be related to some pax tar archives, where the first, and only the (few) first 512 tar blocks(s), do not seem to have a valid checksum set.
