When running heaptrack on something that uses a lot of templates, like std::string, the flamegraph becomes unreadable because all the template arguments are obscuring the function name. Some suggestions:

- Elide the function name in the middle instead of cutting it off a the end
- Collapse long tempate arguments: Instead of "std::map<std::basic_string<bla bla bla>, blub blub blub>::operator[](std::string &const)", say just "std::map<...>::operator[](std::string &const)"
