`cir2qraw` subprocess never exiting causing program to hang

[CyanBlob]

Hi everyone,

I'm using pyqspice with the latest qspice64 version (the build from July 18th).

I'm running into an issue with the cir2qraw function (specifically here: https://github.com/Qorvo/PyQSPICE/blob/main/src/PyQSPICE/qspice.py#L162). The issue is that the QSpice subprocess never exits for some reason, despite seemingly finishing the task of creating the qraw file. I can work around this by adding a timeout, but that is not ideal. Is there some reason why this subprocess would not exit normally?

Thanks!
