- update the implementation of ParserHelper from locale-based std::to_string, std::stod, std::stoull, to locale-independent function std::from_chars and std::to_chars.
- rename TerminalHelper to ConsoleHelper.
- switch to CMake build system and delete original project files because Visual Studio supports CMake project debugging.
- there is a UTF-8 bug for library after switching, but I don't know why it happends. maybe fixed in future.
