Blocking Calls on Android

[krrish-sehgal]

PR1 for #429

Description

Usage of method channel to invoke blocking functionality, that rejects and silences the incoming calls.

• Method Channel Implementation and Control Flow: -A common method channel made names coms.apps.blt/channel and updated in report_bug as well to ensure clipboard paste still works. -Asking of permissions -Handling spam list updates -Registering a SpamCallBlockerService to run in the background that intercepts the calls.

  New Dependencies in gradle folder

  The following dependencies are required for this change:

• org.greenrobot:eventbus:3.2.
• com.jakewharton.timber:timber:4.7.1
• pub.devrel:easypermissions:3.0.0

To make sure it properly runs , we currently have to paste this in terminal manually: " adb shell cmd role add-role-holder android.app.role.CALL_SCREENING com.apps.blt" In time, i would like to find a programmatic approach for this.
