* @param src Path to origin model from Caffe framework contains single
* precision floating point weights (usually has `.caffemodel` extension).
* @param dst Path to destination model with updated weights.
* @param layersTypes Set of layers types which parameters will be converted.
* By default, converts only Convolutional and Fully-Connected layers'
* weights.
*
* @note Shrinked model has no origin float32 weights so it can't be used
* in origin Caffe framework anymore. However the structure of data
* is taken from NVidia's Caffe fork: https://github.com/NVIDIA/caffe.
* So the resulting model may be used there.
