Add more examples

[seanmor5]

We should have a number of examples for different types of problems. An interesting notebook is compare and contrasting Exgboost, Axon, and Scholar on the same problems.

Making notebooks will be much easier once we have precompiled .so to use so CMAKE doesnt have to be in the Livebook environment. Not a blocker necessarily but just in case someone wants to contribute -- just know that your environment might require some tuning.

Is the lack of precompiled .so still an issue? If so, perhaps some non-notebook examples would suffice as a workaround?

Hey, thanks for asking! No, that is no longer an issue as each release now has precompiled libraries. Here's the latest release:

https://github.com/acalejos/exgboost/releases/tag/v0.3.2

They will automatically be fetched when you install with Mix.

@acalejos Awesome, thank you!

Would you accept PRs for examples? One I have in mind is for Quantile Regression. The documentation references a worked example:

exgboost/lib/exgboost/parameters.ex

Line 418 in cfc6c04

* `:reg_quantileerror` - Quantile loss, also known as pinball loss. See later sections for its parameter and Quantile Regression for a worked example.

But I couldn't find one. I ended up getting something working on my end, but I think a worked example would've helped me get there much quicker.

If you are, I was thinking of adapting this example from scikit-learn:

https://scikit-learn.org/stable/auto_examples/ensemble/plot_gradient_boosting_quantile.html

PRs are more than welcome! That sounds like a great example to add. Looking forward to seeing it. Let me know if you run into any road blocks.
