Support for Numpy 2.0

[sanurielf]

HI,

As reported in conda-forge/ta-lib-feedstock#45 ta-lib builds are failing against future Numpy 2.0. Any plans to support this? If so we can use this issue to track the implementation.

It would be nice. My understanding is that it requires Cython support first.

I took a look at the builds error, and seems it is a Cython problem as reported in cython/cython#6249

talib/_ta_lib.c:10268:41: error: no member named 'subarray' in 'struct _PyArray_Descr' __Pyx_INCREF(((PyObject*)__pyx_v_d->subarray->shape));

So, totally agree with you @mrjbq7 , we should wait for a Cython stable support.
