Unable to start, syntax error

I've installed this script on the latest Automatic1111 as well as the commit before the March 25'th updates, I'm seeing the following error on both:

Hi thanks for reporting this! I got the same issue reported on reddit as well.
It's to do with the match statement, not being recognized in all python versions.

So in order to solve, I've rewritten this part to just use normal if statements. It should work now! You can get the latest version from github.

If there is anything else, please let me know.
