Feature Request: Add base64 string support to logo and icon keys

[pitrsin]

The following keys currently expect a local or network path for an image:

• Logo
• LogoDarkMode
• NotificationIcon
• StatusBarIcon

It would help streamline configuration of SupportApp if these keys could interpret an image encoded as a base64 string.

We use Nudge in our environment and it includes support for deploying icons through a base64 string, allowing our one configuration profile to include everything needed for the application: https://github.com/macadmins/nudge/wiki/userInterface#icondarkpath

Thanks!
