New Analyzer: QR Code Parser

[bytinbit]

Feature description
Parse images that contain a QR code and extract its contents.

Describe the solution you'd like
An analyzer that takes an observable of the type "file", and, if it's an image, checks for a QR code, parses it and returns the content. The result can be saved as new URL observable.

Additional context
I already have a working example and need to figure out how to submit it securely for review.
