- extract the identified logo and save it as a png file to filesystem

- the logo could also be only in black and white (mostly scans are only B/W)

MS2: real world handling milestone

- ensure your code is able to handle bad quality scans (e.g. taken with a smartphone) or a bad scanning device. Means dust-stripes and dust-spots need to be cleaned first.

- we do not need any UI we are fine if you call your code from a JUnit-test or if you call your code from a main method. In both cases ensure your code is cleanly structured in its own class and not implemented in one monster-size-method.

MS3: tests milestone

As test cases we will also take this logos for tests:
