One Call API 3.0

This release adds support for the One Call API 3.0 and rewrites a lot of the library.

What's Changed

• One Call API 3.0 by @henrik-dmg in #13
  • Weather is now Codable, to make caching easier/possible

Full Changelog: 5.0.0...6.0.0

Concurrency support

This release adds support for Swift 5.5 new concurrency features as well as some new properties for the weather responses

Version 4.0.0

I've made some breaking changes, so my early Christmas present to you is version 4.0.0.
Most notable changes:

• Renamed HPOpenWeather to OpenWeather
• Updated some method signatures
• greatly simplified decoding of responses which improves readability
• expanded documentation
• added weather alerts

The Housekeeping Update

Changes in this version:

• dependencies were updated, including some fixes to the completion handling of the networking stack
• the completion is now called on the correct queue if the weather request could not be constructed

Combine Publishers

This release brings you Combine publishers for weather request and automatic response decoding. Here's an example:

let someCoordinate = CLLocationCoordinate2D(latitude: 42.989, longitude: -25.128)
let request = WeatherRequest(coordinate: someCoordinate)

let cancellable = request.makePublisher(apiKey: TestSecret.apiKey)

cancellable will be a publisher of type AnyPublisher<OpenWeatherRequest.Output, Error>

Support for custom URLSession

3.4.0

Support for specifying finishing queue

Also refactored towards global settings and not having to set language and API key on every request

Fix init is inaccessible due to internal protection level

This closes #4
