…uild Compute next highest power of 2 to fix issues when using code: const size_t npoints = next_pow2(npoints_raw); The original code (pow(2, ceil(log2())) has some border effects when built with MSYS2 mingw64 "Release" mode as it does not compute correctly the highest power of 2 for example with parameter 100000 it was returning 131071 (instead of 131072) which crashed ffts. This implementation fix issue ngscopeclient/scopehal-apps#295
