Add ringtone from file

[mahmood-heja]

Hi

thx to make this plugin

I suggest an add fun to set ringtone from file like this

static Future<String> setRingtoneFromFile(File file) async {
   
   final String result = await _channel
       .invokeMethod('setRingtone', {"path":  file.path});

   return result;
 }

I've added setRingtoneFromFile method in my fork: https://github.com/timekone/ringtone_set

I hope this helps.
