Simulating CTF with pre-CTF noise doesn't work

[jamesmkrieger]

First I had a problem that I fixed in #881. Now there's another one:

00001: Traceback (most recent call last):

Probably this was an old functionality that was lost since numpy 1.17 or so. We now have to initialise the generator first and I have a fix to do that.
