feat: add experimental support for normalized responses

[ghostrider-05]

• The functions simplifyFromQuery and normalizeFromQuery will perform the same transformations as mentioned below but are typed based on the query to give the output type.

Adds two new response types:

normalize:

• flattens all attributes, included and relationship fields to one object.
• Exposed on the client with <Client>.normalized

simplify:

• Will return the same as normalize with camelCase keys
• Expose on the client with <Client>.simplified

Changes this PR makes

• fix(PatreonOauthClient): remove undefined from return types
• fix(PatreonOauthClient): correctly use cursor for paginating
• feat(rest): add timeout option to client
