[Feature request] Automatic Offline Mode + Selectable Carplay Offline Category

[brokoler]

Hello,

after using Amperfy in my car I had several issues with cached songs today. I wasn't able to search for them via Carplay, when I clicked on a category Amperfy tried to contact my server when I was offline.

Offline mode exists already, but probably following could be added in future:

• Automatically enable offline mode when the Airsonic / Subsonic server is not reachable
• Automatically disable offline mode when the Airsonic / Subsonic server is not reachable
• Add a Carplay category "Downloaded Files" which allows to forcefully play only cached songs / albums

Added a new tab to CarPlay which only contains the downloaded elements:

Automatically enable/disable offline mode will not be supported for now. If the user activates OfflineMode no communication should go out. If Amperfy automatically disables OfflineMode (go to OnlineMode) can lead to false deactivation.
