[clang-tidy] cert-err33-c false positive on user-defined function named timer

1. git clone https://github.com/LegalizeAdulthood/iterated-dynamics
2. git checkout 53c6c9909e2d2e320ccedc55e9ed2d59fbcb1705
3. configure CMake project, optionally using the provided CMakePresets.json
4. Browse to libid/bifurcation.cpp, line 471 on the call to the timer function
5. IDEs (and presumably clang-tidy from the command-line) flag the call to timer as a cert-err33-c violation
6. The documentation doesn't list the function timer as one that would be flagged by this check
7. Even if a system function called timer (I couldn't find any such function) existed, if a user-defined overload is distinguished from the system function, then it still shouldn't be flagged as a violation.
