Calibration plot

[raminsalmas]

I'm wondering it there's any function in the scikit-survival to generate 'calibration plot'?

PR #101 started to implement this, but it has been dormant for a while now.

Thanks for your reply @sebp and all your work on scikit-survival. Is there cross-compatibility between model objects in scikit-survival and lifelines? lifelines has a function to create calibration plots and it's based on a different implementation than that proposed in PR#101.

I ask since I wish to check calibration visually for more complex models (e.g. random survival forests) that are supported in scikit-survival but not in lifelines.

@vinyasHarish95 Thanks for pointing out the function in lifelines. I'll have a look to check in which regards it differs.,

Thanks @sebp - I have some bandwidth over the next few weeks to take a stab at implementation (but might need some help (e.g. around designing appropriate unit tests) as I've never contributed to an open source project before.
The lifelines implementation is only ~100 LoC so does not seem so bad.
Do let me know if you're interested in working on this - I can imagine other users would benefit from this feature.

It certainly would be nice to have and contributions are always welcome. Feel free to open a PR and I'd be happy to give feedback.
