Unable to install on Python 3.11

Describe the bug

Due to the use of the cchardet dependency, which seems to have been abandoned (PyYoshi/cChardet#77), BlackSheep fails to install on Python 3.11:

/usr/bin/clang -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -pipe -Os -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk -Isrc/ext/uchardet/src -I/opt/local/Library/Frameworks/Python.framework/Versions/3.11/include/python3.11 -c src/cchardet/_cchardet.cpp -o build/temp.macosx-12.0-x86_64-cpython-311/src/cchardet/_cchardet.o
src/cchardet/_cchardet.cpp:196:12: fatal error: 'longintrepr.h' file not found
  #include "longintrepr.h"
           ^~~~~~~~~~~~~~~
1 error generated.
error: command '/usr/bin/clang' failed with exit code 1

EDIT: After manually installing Cython, I can bypass the above error, but now get the same error for blacksheep directly:

/usr/bin/clang -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -pipe -Os -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk -I/opt/local/Library/Frameworks/Python.framework/Versions/3.11/include/python3.11 -c blacksheep/url.c -o build/temp.macosx-12.0-x86_64-cpython-311/blacksheep/url.o -O2
blacksheep/url.c:198:12: fatal error: 'longintrepr.h' file not found
  #include "longintrepr.h"
           ^~~~~~~~~~~~~~~
1 error generated.
error: command '/usr/bin/clang' failed with exit code 1

Seems to be related to cython/cython#4461.

@mohd-akram thanks for the information, I’ll look into charset_normalizer. For now, this specific issue can be closed. Before I saw your comment, I released the new version 1.2.8 to PyPI, and it includes wheel packages for Python 3.11.
