Addressing NumPy security alert

[john-science]

NumPy has released the following security alert: GHSA-6p56-wp2h-9hxr

This PR addresses that alert. Though it may affect some floating point calculations down stream, so some testing of dependent projects in the ARMI ecosystem should be done before this is merged into master.

NOTE: There is a lot of testing that will need to be done before merging. Please do not hit "Merge" this PR for me.

All the unit tests in this branch run fine on my Linux workstation. I see the old NumPy bound existed because there was a NumPy-related "bug in Windows".

I don't have the foggiest guess what that bug might be, but I will test this PR on a Windows machine before merging into the repo.

@john-science are waiting on something to merge this in? I assume this will break some down stream stuff on our internal end with using previous numpy versions.

[john-science]

@jakehader You said we needed to do some downstream testing before we could merge this. We've been too busy to talk about getting that done.

[jakehader]

This will probably break some stuff downstream for us but let's just pull the trigger and then fix things as needed. Especially if this is technically a security concern we should address. Oh! One more thing - should we update the version of the framework because of this change?

[john-science]

@jakehader If you think we can just roll with it, that's good enough for me.

And the version bump! You are totally right. I will fill out the release docs page and bump the version right now, and Merge this morning.

Cheers!
