Describe the issue:

In numpy/_core/src/npysort/quicksort.cpp
if (sizeof(T) == sizeof(uint16_t)) should be modified with "constexpr", and the same applies to the followingif (sizeof(T) == sizeof(uint32_t) || sizeof(T) == sizeof(uint64_t)).
Other similar parts of the code have already been updated, so this seems to be a missed case.

Reproduce the code example:
