MAINT: Silence integer comparison build warnings in assert statements

[seberg]

Just a few warnings less on my gcc (debug) build at leas (was annoying me while writing larger amounts of new code and trying to find the relevant actual warnings)

[seberg]

Hmmm, maybe it should be uinptr type or something instead of npy_uintp in principle.

What is the actual warning printed by the compiler?

[seberg]

numpy/core/src/umath/simd.inc.src: In function ‘sse2_sqrt_FLOAT’:
numpy/core/src/umath/simd.inc.src:1020:14: warning: comparison of integer expressions of different signedness: ‘npy_intp’ {aka ‘const long int’} and ‘long unsigned int’ [-Wsign-compare]
 1020 |     assert(n < (VECTOR_SIZE_BYTES / sizeof(@type@)) ||
      |              ^

Let's go with the current implementation, thanks @seberg
