FIX: make sure to assign string literals to `const char*` #260

Assigning string literals to char* has been illegal since C++11, but Visual Studio only started to enforce this in C++20 mode, where the /permissive flag is disabled by default. With this small change, the project now also compiles in Visual Studio's C++20 mode.
