[N] Feedzai released FairGBM (fairness-aware LightGBM) in open-source for non-commercial uses

[Feedzai](https://www.linkedin.com/company/feedzai/) just released FairGBM in open-source for non-commercial uses. FairGBM is an efficient, easy to use, flexible extension of LightGBM with additional fairness constraints (via a proxy-Lagrangian formulation).

Github: [https://github.com/feedzai/fairgbm/](https://github.com/feedzai/fairgbm/)

With FairGBM you can have \*both\* high model performance and high fairness. See image below: FairGBM (blue circles in the image) can closely approximate the model performance of LightGBM (orange circles) and the fairness of other fairness-aware algorithms (red and green circles).

Additionally, FairGBM is:
\- fast: 3x to 6x …
