Python3.11 is not compatible with cchardet

[nailend]

Python3.11 is not compatible with cchardet, however cchardet is abandoned. More info here: https://bugzilla.redhat.com/show_bug.cgi?id=2021804

There is a fork fixing this https://github.com/faust-streaming/cChardet

However, I fixed python to <3.11 to solve the problem

Note: This error originates from the build backend, and is likely not a problem with poetry but with cchardet (2.1.7) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "cchardet (==2.1.7)"'.

Thanks for fixing python version. This bug is coming from very old dependency tableschema. As tableschema has been replaced by frictionless, but frictionless is currently not working with oemof.tabular. Thus fixing python to <3.11 is the simpliest solution for now.
