separate compiler flags

- Needs to be done for clang to recognize them
Avoid data copy in cy_expect_psi_csr

- Use conj() from complex_math.pxi instead of creating new numpy array
each time.
Add ability to reuse seeds
removed unnecessary numpy imports
Move seeds out of config
fix extra runtime when near times is tlist
removed unnecessary for-loop
Call correct zvode step mode

- Need to bypass much of the scipy code to get this to work, but the
mcsolver much faster now.
Fix error in mcsolve

-Revert to old code with for-loop to get rid of error
Added back seed reuse an cleanup
Added mcsolve reuse seeds test
Added notes on seed reusing
