gufo_loader VS snecs

Gufo Loader is the flexible Python plugin infrastructure framework. We'd used this approach in the NOC - an open-source network management system and finally decided to release this component as the independent package. Very useful tool to build extendable and reliable python applications and services.

I tried to use Snecs but its type-hinting was not robust enough for VSCode's Pylance. I had to throw it out and make my own simplified version of ECS. I can add single arbitrary components to entity objects but I don't have a global registry for them. Which is too bad since the global registry is a useful and important part of ECS.

I've been closely looking at the Python ECS libraries Snecs and Esper. I was hoping I could use one of them to fix the Python tutorial without making the tutorial about writing an entity-component engine. What I actually want would be a Python ECS library with NumPy for static types, but a library I did find for that didn't have a good enough license for a tutorial. For now I'll be okay with dynamic types just so I can fix my current problems, and I'll think about performance some other time.
