Add the flowing new sources

[peaklabs-dev]

1. Add the DJI Fly app for Android as a source, like signal or telegram. This will greatly improve the update experience with the apk version of the app. There is no official Play Store version, so all Android users have to use the apk version, and it would be great if the apk could be updated via obtainium, link to the apk: (https://www.dji.com/ch/downloads/djiapp/dji-fly), direct download: (https://service-adhoc.dji.com/download/app/android/3b03cb95-bc4b-4b62-b4ab-9cf977d77309)
2. Add drone hacks companion android apk to the sources, download link: (https://drone-hacks.com/download)

These sources would be a great addition to the app. Thank you very much.
