Samples from recent open source models.

[haesleinhuepf]

This PR contains:

• a new test-case for the benchmark
  • I hereby confirm that NO LLM-based technology (such as github copilot) was used while writing this benchmark
• new dependencies in requirements.txt
  • The environment.yml file was updated using the command conda env export > environment.yml
• new generator-functions allowing to sample from other LLMs
• new samples (sample_....jsonl files)
• new benchmarking results (..._results.jsonl files)
• documentation update
• bug fixes

Related github issue (if relevant): closes #62 , partially solves #59

Short description:

• I had to resend PR Samples from recent open source models. #62 by @jkh1, because the files in Samples from recent open source models. #62 contained colons :, which screwed up git/filesystem

How do you think will this influence the benchmark results?

• These are new samples from other LLMs, existing benchmarks will not change

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

• These open-source models are quite recent and we can learn about how they perform.
