closes #26

• 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.
• The methods that return the raw API responses can still be found on <Client>.api

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

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

BREAKING CHANGES

• client: all fetch* and paginate responses are now simplified, not the raw payload
