[v2.3.0] - 2023.05.03

Added

• Optional destination_airport keyword argument to the cheap flights endpoints,
  in case you only care about the cheapest flight to a single airport.
• Improved type hints on the main API methods.
• In regard to the availability API:
  • Ability to grab a session cookie for use by the availability API.
  • Exceptions raised when the availbility API declines to provide results,
    for reasons such as rate limiting or the lack of a session cookie.
  • Thanks to @dolohow.

Changed

• When the library hits an exception parsing an API response, it will now also log the original query params.
  • Thanks to @dolohow.
• Small refactors, additional type hints

Fixed

• currency is now only added as a parameter on calls to get_cheapest_return_flights whenit is configured, identical
  to get_cheapest_flights.
