Make BarCode object do its own translation of .uri → .path

But leave behind .uri for backwards-compatibility.

 [here](https://zxing.github.io/zxing/apidocs/com/google/zxing/BarcodeFormat.html).
 
 The `decode()` method accepts an image path (or list of paths) and takes optional parameters `try_harder` (boolean), `possible_formats` (list of formats to consider), and `pure_barcode` (boolean).
