Using std::stringstream simplifies the code.
The <SP> element is needed between two >String> elements.
Remove also some unneeded spaces in the ALTO output.

Instrumented code throws this runtime error during OCR:
../../src/api/baseapi.cpp:1616:5: runtime error: load of value 128,
which is not a valid value for type 'bool'
../../src/api/baseapi.cpp:1627:5: runtime error: load of value 128,
which is not a valid value for type 'bool'
If there is no font information (typical for Tesseract with a LSTM model),
the font attributes got random values resulting in wrong hOCR output.

All also a C++ implementation with more aggressive compiler options
which is optimized for the CPU where the software was built.
It is now possible to select the function used for the dot product
with -c dotproduct=FUNCTION where FUNCTION can be one of those values:
* auto selection based on detected hardware (default)
* generic C++ code with default compiler options
* native C++ code optimized for build host
* avx optimized code for AVX
* sse optimized code for SSE

This reduces the code size for intsimdmatrixavx2 from 2700 to 2668
and slightly improves the performance for fast models with AVX2.

This improves performace for the "best" models because it
avoids function calls.
The compiler also knows the passed values for the parameters
add_bias_fwd and skip_bias_back.
