Cached KeyImages cannot be stored

[wojciechsura]

I created and stored a number of KeyImage images to improve performance during switching screens. However, during using such images, I ran into an exception:

Type:        System.ArgumentNullException
Message:     Value cannot be null. (Parameter 'key')

Workaround: Disable caching when creating Stream Deck device instance. Also. don't store KeyBitmaps, create them every time they are needed.
