fix: import array from numpy instead of scipy

Description
Remove use of scipy.array in parallel.py, which is incompatible with scipy==1.12
Fix #2300

Thank you for the fix.

There are other issues with scipy 1.12 for v4 in steadystate.
Are you interested in fixing them here or do you prefer we merge this as is and fix the rest in another PR?

There are other issues with scipy 1.12 for v4 in steadystate.

At a glance, it is not clear to me where the issues are. I confirmed that each scipy function used by steadystate.py exists and is successfully imported.

[Ericgig]

The issue is not with import, but deprecation warnings.
For our tests, warnings are considered errors.
This is why the tests using scipy 1.12 are still failing.
We will fix this on our side.

Thank you again for your contribution.
