Additions, changes
~~~~~~~~~~~~~~~~~~
- Added YUV(A) 4:4:0 pixel format constants
- Added ``SetFilterProp``, ``GetFilterProps``, and ``SetFilterPropPassthrough``:

* ``SetFilterProp`` — automatically inject a frame property on the output of a named filter

Build environment, Interface
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Bump to interface version 13 for new color constants
- introduce ``AVS_RESTRICT`` to ``avs/config.h`` (compiler invariant c++ ``__restrict``)
- AVX512: CMake to recognize ``*_avx512b.*`` and ``*_avx512.*`` file pattern, add compiler specific AVX512
compile flags accordingly (AVX512 Base and Ice Lake extensions)
