Allow to load add ccViewer in Files app

[prabirshrestha]

This added support for accessing files from ccViewer. https://github.com/lithium0003/ccViewer/issues/2. I was expecting the opposite instead i.e. from Files app I can view files and folders from ccViewer. Sorry if I wasn't clear. I didn't think of #2 but that seems also a good feature that I will be using.

This allows me to easily use Save to Files from a different app and select ccViewer. Files app also supports compress and uncompress so features like those can be got for free.

It means that showing the ccViewer folders when open the Files.app? My understand is that you want to import (and upload) files from other app with Files.app, is it correct?

Yes. Basically I want ccViewer to be shown here in the Files app location. This would allow me to easily import export from other apps but use ccViewer for encryption.

Thanks for information. It means that app should implement FileProvider. I'll check it and try.
