createFile fails on network content providers #151

First off, thank you for the awesome plugin!
Describe the bug
Operations that require network calls (i.e. createFile on an external content provider) fail due to Android blocking network calls on the main thread. (If curious see nextcloud/android#8028).

To Reproduce
Attempt to create a file on an external network content provider.

Expected behavior
Files can be created on network content providers.

Smartphone (please complete the following information):

• Device: Google Pixel 7
• OS: Graphene OS
• Content Provider: Nextcloud
• Version: Android 14

Additional context
I was able to quickly fix the problem on a fork of the plugin by running the API actions in the IO thread (Demizo@636c9e3)
