Getting error: res.headers.raw is not a function

[M-Nasab]

I get this error when i use this library:

Uncaught (in promise) TypeError: res.headers.raw is not a function at fetchCookie (index.js?a60e:41)

This could happen because fetch-cookie assumes you use node-fetch v2 and may fail if you aren't:

fetch-cookie/index.js

Lines 40 to 41 in 4fcbe62

	// node-fetch v2
	const headers = res.headers.raw()

What fetch implementation are you using in what environment?

FWIW I've got this happening right now, using node-fetch 2.6.1. Replicated in both Firefox and Safari.

Hey! I just published v2.0.0 with improved support for various fetch implementations!

headers.raw was pretty specific to node-fetch but now fetch-cookie also supports any fetch implementation compatible with the WHATWG Fetch standard API (as long as it exposes the set-cookie header)
