make write_lef and others write out files atomically

[oharboe]

Description

A half-written .lef file can be lying around after a crash which complicates e.g. deltaDebug.py.

Suggestion:

1. modify all write_* commands to write to a temp file
2. when the write completes, rename temp file to final name

This way there are no partial files lying around

Hello @maliberty @oharboe , I'd like to work on this issue. Could you please assign it to me ?

[oharboe]

@annapetrosyan26 You can simply create a pull request without being assigned this task, I don't have the role to assign github issues in this project.

I haven't seen that @maliberty assigns github issues to new contributors, but perhaps that's something that would be approperiate?

[annapetrosyan26]

Thank you @oharboe for the clarification. Then I'll work on the issue and once the code is ready I will create a pull request.
