Add SEIR model template

[speed1313]

Thank you for your great and interesting work!

I prepared a custom template of the SEIR model, a differential equation model for predicting infectious diseases.
For more details, please visit my blog post, where I wrote about an experiment using this template.

Note
To ensure this template code runs correctly, the line

AI-Scientist/ai_scientist/perform_experiments.py

Line 64 in 8383c8a

results = {k: v["means"] for k, v in results.items()}

in the run_experiment() function needs to be changed to

results = {k: v for k, v in results.items() if k != "solution"}

Would you be able to add a dummy means field for your new variable so we don't have to make a change that could be hard to maintain in the future? Thanks so much!

Thank you for reviewing!
I added a dummy means and a dummy dataset name. We can run this template without any modification now.
