Handle badly formatted JSON-LD data.

Some web pages contain badly formatted JSON-LD data, e.g., [an example](https://www.debenhams.com/webapp/wcs/stores/servlet/prod_10701_10001_60742+1515029001_-1) The JSON-LD in this page is: ``` { "@context": "http://schema.org", "@type": "Product", "name": "Black 'Clint' FT0511 cat eye sunglasses",...

``` def rgba2rgb(img): return img[:,:,:3]*np.expand_dims(img[:,:,3],2) ``` This function does not remove the alpha channel but multiplies RGB channel with the alpha channel in np.uint8 range. This seems a bug.
