1537ecd931 * added depth-wise convolution; gives ~20-30% performance improvement in MobileSSD networks 
* hopefully, eliminated compile warnings, errors, as well as failure in one test

* * fixed a few typos
* decreased buffer size in some cases
* added more optimal im2row branch in the case of 1x1 convolutions
* tuned fastConv to reduce the number of passes over arrays

Merge pull request #18019 from pemmanuelviel:pev--multiple-kmeans-trees 
* Possibility to set more than one tree for the hierarchical KMeans (default is still 1 tree).

This particularly improves NN retrieval results with binary vectors, allowing better quality
compared to LSH for similar processing time when speed is the criterium.

* Add explanations on the FLANN's hierarchical KMeans for binary data.
