Stream Deck support

🚨 Breaking

• Relocated to SharpDeck.Events.StreamDeckAction to top level SharpDeck.StreamDeckAction.
• Re-aligned namespaces of events (received) / messages (sent) to match Elgato SDK terminology.

⭐ Added

• Support for SDK 4.1
  • didReceiveGlobalSettings
  • didReceiveSettings
  • getGlobalSettings
  • getSettings
  • logMessage
  • propertyInspectorDidAppear
  • propertyInspectorDidDisappear
  • setGlobalSettings
• Support for SDK 4.3
  • systemDidWakeUp
  • Added device name to registration info.
• StreamDeckAction{TSettings} base class.
• RequestId to property inspector methods, allowing for responses to be identified more easily (e.g. with promises).
• StreamDeckXL and StreamDeckMobile to DeviceType.

🐞 Fixed

• Fixed JSON serialization casing inconsistencies when using JObject (specifically action settings).
• Fixed openUrl event.
