On machines which only have python 3.10 installed, running pip install qsimcirq gets version 0.9.5 with the following error message for later versions: none of the wheel's tags (<wheel>) are compatible.
It is possible to work around this by installing an older python version (e.g. using pyenv), but ideally users shouldn't need to worry about their python version as long as they have at least python 3.7.
To fix this, we should add a python 3.10 wheel to the release.
