README.python.md: Add some notes for Windows
...
Note that the DLLs for HarfBuzz and its deps must be found %PATH% on Windows so
that pygobject is able to import and use HarfBuzz in Python scripts.
Also note that for Visual Studio builds, it is recommended that Visual Studio
2019 or later is used for the build, possibly in regards with how the
preprocessor handles C++ code when running g-ir-scanner.

Unfortunately hb_array_t::begin/end are faster than its _begin/_end.
As such, a range loop on array itself is faster than range loop on
pipeline starting with array. Rework code to loop on the array always.
