error handling improved; fixes #5 preserve EXIF

 Same as above just that it takes in only one file instead of a whole array of files.
 
+### Get EXIF oriented image 
+#### `getEXIFOrientedImage(image:HTMLImageElement): Promise<HTMLImageElement>`
+Method that returns an image respecting the EXIF orientation data.

 ## Contribute 
 Due to the lack of other algorithms that also reduce the filesize of an image by reducing the quality until it fits a certain limit, help to find the best possible algorithm to do so is much appreciated.
 The current algorithm can be found here: https://github.com/bergben/ng2-img-max/blob/master/src/img-max-size.service.ts.
