Please verify that the --pid_suffix option works as intended

Recent versions of viztracer don't seem to append the PID to the filename. Instead it creates result.json.

viztracer --pid_suffix single_process.py appends the PID in version 0.12.3 but not in 0.15.6

This is a regression and the issue is created at #346 . I'll fix it soon, thanks!

Thank you, do you think the example viztracer --pid_suffix single_process.py should work now?
I'm on the latest commit but no PID is appended to the filename still.
