v0.1.0 - First official release

I am super excited to announce DiffeRT v0.1!

This version marks an important step for this package, see the first milestone.
Some important features are still missing, see the second milestone, but I feel this project can already be used for research, as I did in the past for conference articles like Comparing Differentiable and Dynamic Ray Tracing: Introducing the Multipath Lifetime Map and Towards Generative Ray Path Sampling for Faster Point-to-Point Ray Tracing.

If you are curious about this tool, feel free to give it a try and don't hesitate to report any bug or question you might have about it!

Future changes will now be documented in a changelog, and a strict versioning policy will be adopted to avoid surprising breaking changes.
