Warning messages with CUDA nvcc compiler

[tmartin-gh]

When using the NVIDIA compiler nvcc, the fmtlog library has some warnings.

First warning:
fmtlog/fmtlog-inl.h(71): warning #170-D: pointer points outside of underlying object case 18: *(uint16_t*)(s + 16) = *(uint16_t*)(digit_pairs + ((num % 100) << 1)); num /= 100; ^ detected during: instantiation of "void fmtlogDetailT<___>::Str<SIZE>::fromi(T) [with ___=0, SIZE=4UL, T=int]" at line 279 instantiation of "void fmtlogDetailT<___>::resetDate() [with ___=0]" at line 101 instantiation of "fmtlogDetailT<___>::fmtlogDetailT() [with ___=0]" at line 541 implicit definition of "fmtlogDetailT<0> fmtlogDetailWrapper<__>::impl [with __=0]" at line 541

Second warning:
