Plugin fail to load on new system setup using python 3.10

[jaketri]

It look like issue is with old version of sqlalchemy which use removed/deprecated attribute.

Here is copy/paste section from octoprint.log with the error:

Based on comment from #23 I tried to force SQLAlchemy update to 1.3.23. I can confirm that plugin is working fine on python 3.10.1 after the SQLAlchemy update to 1.3.23 !

Running Octoprint 1.8.0RC2 & Python 3.10.4

Same - I restored my backup to a diff PC from a pi. Running Python3.10 and this plugin refuses to install. It appears as if it does but I get a pop-up saying 'unknown' plugin installed. Still does not show in the installed plug-in list.

I can confirm this issue. Restore Backups from OctoPi 1.7.x to actual RC wont work for me either
