util: Introduce ToIntegral<T>(const std::string&) for locale independent parsing using std::from_chars(…) (C++17)
util: Avoid locale dependent functions strtol/strtoll/strtoul/strtoull in ParseInt32/ParseInt64/ParseUInt32/ParseUInt64
fuzz: Assert equivalence between new and old Parse{Int,Uint}{8,32,64} functions
test: Add unit tests for ToIntegral<T>(const std::string&)
