stapi-fastapi/v0.8.0

Added

• RootRouter Callable get_orders now requires an additional value in the result tuple that is a count of the total number of orders
  that will be returned from pagination. When this returns Some(int), the value is used for the numberMatched field in
  FeatureCollection returned from the /orders endpoint. If this feature is not desired, providing a function that returns
  Nothing will exclude the numberMatched field in the response.
• ProductRouter and RootRouter now have a method url_for that makes the link generation code slightly cleaner and
  allows for overridding in child classes, to support proxy rewrite of the links.
