Notes

• properly ensure RECORD_AUDIO permission is requested during camera initialisation

  • since allowBackup is set to true in the manifest,
  • it is possible for the app to be launched after a fresh install with mIsInPhotoMode=true in MainActivity
  • this commit ensures the audio permission is requested at this point
  • if the user denies it, then it is initialised in photo mode instead

• remove EXIF info after image capture if the user sets config.savePhotoMetadata == false
