Fast Bag of Words

This is a modified version of the original Fast Bag of Words by @rmsalinas.

FBoW (Fast Bag of Words) is an extremely optimized version of the DBoW2/DBoW3 libraries.
The library is highly optimized to speed up the Bag of Words creation using AVX,SSE and MMX instructions.
In loading a vocabulary, FBoW is about 80x faster than DBoW2.
In transforming an image into Bag of Words using on machines with AVX instructions, it is about 6.4x faster.
