Update documentation for multipart/form-data requests

[lorenzodejong]

Thanks for open sourcing this library, saved me quite some time while implementing my API proxy.

While working with multipart/form-data requests i've noticed that the Next.js bodyParser tries to parse the body, causing it to corrupt the binary content of all files in the request. Therefore (in my case) it's desired to disable the bodyParser entirely in the API route (https://nextjs.org/docs/api-routes/api-middlewares#custom-config).

export const config = {
	api: {
		bodyParser: false
	}
};

This library handles all other requests/content-types correctly. Perhaps it would be an idea to document this to safe others some time with similar issues.

Does turning off the bodyParser cause any issues with other types of requests (what is it there for)?
