Update python-ee

[pyee 8.1.0](https://pypi.org/project/pyee/) is the latest release but the current requirements are blocking it.

https://github.com/labthings/python-thingserver/blob/119d9ef3f4efe0ca08aedbca5e61564e9ec8fca8/pyproject.toml#L20

Would it be possible to get an update?

Thanks in advance.
