• new generator-functions allowing to sample from other LLMs
• new samples (sample_....jsonl files)

Related github issue (if relevant): closes #102

Short description:

• I was benchmarking llama3.1 8b

How do you think will this influence the benchmark results?

• It is a new model, introducing a new datapoint, just a bit a head of llama3:8b

Why do you think it makes sense to merge this PR?

• To stay up-to-date with recent models.

I screwed this PR up by submitting [broken] 70b benchmarking to the same branch. Will later iterate on this
