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.

The new header file ccutils/tesstypes.h also prepares support

size and coordinates (still unused).
FloatToDouble is now a local function.
