Add support for and require pagy v43

Pagy v43 contains some major changes to the API, primarily moving all
options into Pagy.options, and forcing you to choose a paginator instead
of directly using the Pagy class. This commit requires the use of Pagy >= v43
going forward, and updates the integration to use the new API.
