    lang/cython-devel: add port
    
    Add devel version of cython. Apart from that 3.x cython branch is
    where all the development goes on, 0.29.x only gettig backported
    bugfixes, this is currently the only version which supports python
    3.11. Because of that, wire USE_PYTHON=cython to cython-devel for
    python >= 3.11 in Uses/python.mk as well and limit supported python
    versions with <= 3.10 for cython.

+The Cython language makes writing C extensions for the Python language
+as easy as Python itself. Cython is a source code translator based on
+the well-known Pyrex, but supports more cutting edge functionality and
+optimizations.
+
+The Cython language is very close to the Python language (and most
+Python code is also valid Cython code), but Cython additionally supports
+calling C functions and declaring C types on variables and class
+attributes. This allows the compiler to generate very efficient C code
+from Cython code.
+
+This makes Cython the ideal language for writing glue code for external
+C libraries, and for fast C modules that speed up the execution of
+Python code.
