Tfloat patch 3: implements DotProductSSE() for FAST_FLOAT #3493

Commits on Jul 13, 2021

  1. Add TFloat data type for neural network 

    Up to now Tesseract used double for training and recognition
with "best" models.

This commit replaces double by a new data type TFloat which
is double by default, but float if FAST_FLOAT is defined.

Ideally this should allow faster training.
