NumPy has had a way to add a call to a user-supplied function whenever
allocating via PyDataMem_SetEventHook [0]. Python added the tracemalloc
[1] functionality which make this redundant. NumPy also added memory
alloc/free overriding in NEP 49 [2] which will be part of the 1.22
release. I propose deprecating the PyDataMem_SetEventHook function, and
have submitted a PR to do so for 1.23 [3]. Thoughts? Is anyone using the
hook for something that tracemalloc cannot do?
