Fix bug with multiple generic inheritence #626

Closed jcrist closed 6 months ago

jcrist commented 6 months ago

Previously if the same generic base class appeared multiple times in a classes inheritence graph msgspec would error when trying to analyze the class. This PR fixes the bug and adds a test for the behavior.

Fixes #625.
