Cookie encoding / decoding can now be customized

Adds new encode and decode functions to allow customizing how cookies are encoded and decoded. For example, you can bypass the default encoding via encodeURIComponent when adding a URL as part of a cookie:

---
import { encodeCookieValue } from "./cookies";
Astro.cookies.set('url', Astro.url.toString(), {
  // Override the default encoding so that URI components are not encoded
  encode: value => encodeCookieValue(value)
});
---

Later, you can decode the URL in the same way:

---
import { decodeCookieValue } from "./cookies";
const url = Astro.cookies.get('url', {
  decode: value => decodeCookieValue(value)
});
