Add sleep import to eqy_job.py

[AUDIY]

I encountered the following error when trying eqy within oss-cad-suite installed on Windows 11.

Traceback (most recent call last):
File "C:\StandalonePrograms\02_oss-cad-suite\bin\eqy-script.py", line 1260, in
main()
File "C:\StandalonePrograms\02_oss-cad-suite\bin\eqy-script.py", line 1213, in main

sleep(0.1)
^^^^^
NameError: name 'sleep' is not defined

After investigating, I found that sleep() from the time library is not imported.

Therefore, I would like to propose a fix.

Thanks.
