Running clang-tidy readability-implicit-bool-cast on src/detection/Footprint.cc revealed that the wrong overload of SchemaMapper::addMapping is called when given a string literal as the second argument.

We expect it to call Key<T> addMapping(Key<T> const& inputKey, std::string const& outputName, bool doReplace = true);, but instead it calls Key<T> addMapping(Key<T> const& inputKey, bool doReplace = false); because it prefers to cast to bool rather than create a std::string temporary.

I propose we add an overload taking char const*, make it primary and redirect the std::string const& overload to it.
Another alternative would be to find where it is called with a string literal and change it to a std::string.
