Modify methods used in simpleCorsResourcePolicy

I find it that most people build APIs when using wai-cors hence modifying the request to add the other methods essential.

You are free to use the proposed CORS policy when serving your APIs, but it would require the client to make preflight requests and would thus not be a policy for simple cross origin requests. Since this policy would be specific to your API, I think, it is outside the scope of this package.
