Python 3.11 support

[oysstu]

Package does not build for Python 3.11 due to the following line in pyproject.toml.

check_shapes/pyproject.toml

Line 35 in 3969110

python = ">=3.7,<3.11"

Are there any known issues with 3.11?

Sorry about the late reply. If I remember correctly it's because some downstream package has (or had, at the time) that constraint, and poetry won't let us depend on it without that constraint ourselves. It can probably be relaxed now.
