Dependency breaking for Windows installations

[dpesce]

Currently the ehtim package has paramsurvey as a dependency, which in turn uses the resource package:

https://docs.python.org/3/library/resource.html

This package does not work on Windows machines, so installation of ngehtsim breaks.

I don't have WIndows to test, but I'd be happy to hack together a Windows version if I have a person to test. It's just 2 things.

I also don't have a Windows machine to test it on; this issue was initially uncovered through unit tests being run with Github actions in a Windows environment. I think @ryan-chaves-sao may have a Windows machine though?

I think I can YOLO this one in a pull request, it's simple enough of a change. Let me finish being on vacation first (back Jan 9 -- hello from Tokyo.)

I believe it's due to paramsurvey's use of the resource module, which appears to be UNIX-only.
