*: multiple performance improvements like marking `static const` when it makes sense... date: change old stupid heap-based method to a structure which should make copying the thing actually make a copy. also many performance-based changes, like removing the std::tie dependency and forward-declaring nlohmann json *: replace every instance of QString::fromUtf8 to Strings::ToQString. the main difference is that our function will always convert exactly what is in the string, while some other times it would only convert up to the nearest NUL byte
