Add statistics about the labeled objects about make-sense

[SkalskiP]

Hi, @ahmedbesbes! Super idea. For the sake of the university, I had to stop working on MakeSense for a while. But in February I'm going to return to development.

Your idea looks very interesting. What's more, I also like to be aware of these numbers when I prepare a dataset.

@SkalskiP I would like to contribute to this idea if you don't mind. :)

@RolfLobo would you like to implement this task?

Addings some statistics of project would be great to make it easier to report (academically, perhaps).

something like (not sorted but would be great to be added):

Images Status-> (Missing / Corrupted, Blurred, Rejected, Succeed )
Class Ballance -> Under Represented, Over Represented.
Annotation -> Count, Average, Class Represented, Heatmap
Image -> Average Size, Range, Aspect Ratio Distribution, Dimension

The work on that feature is in progress: #268
