MLECO-2458 and MLECO-2476 [Fix] VWW IFM quant step

* Changed image->cc conversion to be similar with preprocessing
  of img_class and vww models: images are scaled maintaing the
  aspect ration and then the centre crop of the correct size
  is taken.
* VWW applies input quantization info to the int8 image
  (prior converted to [0,1] float range).
* Changed adult_blur to a image without person.
* Fix menu print when selecting a specific ifm to run
  (Select message was displayed after typing something)
