**Full Changelog**: https://github.com/zoj613/pyloras/compare/v0.1.0-beta.5...v0.1.0-beta.6

Adds the GAMUS algorithm for oversampling, described at https://arxiv.org/pdf/2103.13823.pdf.

- Adds the `ProWRAS` algorithm for oversampling. It is meant to be an improvement over LoRAS.
- pin minimum numpy version to 1.17.0
- Use numpy's new `Generator` interface internally for random number generation. This changes the results of the oversamplers from previous versions.
- Make sure `LoRAS` makes a copy of the `manifold_learner` argument if not None instead of modifying it in-place.

- Generalizes the 2d manifold learning to allow any manifold learning object that implements scikit-learn's Estimator interface (e.g. using UMAP instead of the default TSNE).

- Improvements in correctness of the algorithm. Pretty sure its correct now!
- Improvements in single-threaded performance.
- added CI and wheel distribution for all platforms.
