Compatibility with numpy 2.0

[Zethson]

Numpy 2.0 is out and lifelines currently does not support it (base requirements restrict to < 2.0). I would like to politely request an unpin if possible.

For sure, we can do this and fix #1618. Let me attempt this tonight.

mmmm this may be more complicated due to autograd not being updated, and #1615 not resolved. I don't expect autograd to update, so we need to figure out #1615 first.

So things are happening with autograd, and some new maintainers have stepped up. I will keep any eye on thier progress.

Apparently a user has confirmed that lifelines works with numpy 2.0 with the latest autograd #1615 (comment) - any hopes for a 0.30.0 release with numpy support soon? :)
