ca177e72f3 hocrrenderer: write scan_res property to the ocr_page 
This will make Tesseract emit the DPI of the document, if known at OCR
time. This is requird to properly interpret the x_fsize (font size)
property of words, since Tesseract scales the font size to the DPI.

See issue #3326 (https://github.com/tesseract-ocr/tesseract/issues/3326)

e5e12f2856 Disable HAVE_FRAMEWORK_ACCELERATE for compilers which fail to compile with it 
g++-10 and g++-11 throw compiler errors in builds with the
Accelerate framework, so disable it for all GNU compilers

ec87dd4d49 Abort LSTM training with integer model (fixes issue #1573) 
Tesseract currently cannot continue LSTM training from an
integer (fast) model.

Report this to users who try it nevertheless instead of crashing
with an assertion.

472f5d9020 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.

f72d4b1fe7 NEON arch: dead ref cycle fix 
When neon_available_ is ON, the DotProduct was set to point to DotProduct,
which should have been DotProductNative, as dotProduct is the *target* global itself:
see simddetect.h --> effectively making that part of the SetDotProduct() call
identical to this (no-op) statement: `DotProduct = DotProduct;`

Also added the Neon check in the Update() API, where it exists together
with the other checks (for AVX/SSE/etc.)

the insert method which returns whether the insertion was possible

    Warning: Invalid resolution 0 dpi. Using 70 instead.
    Estimating resolution as 642

The warning is also shown when the resolution is not used at all
when preparing data for training.

It is now suppressed when there is no resolution information
(resolution == 0).
