Updated reference integrals to reflect current state of the code

[ndmeier25]

I've traced it to the fact that the reference integrals were not updated after PMZ changes in commit c1fb5fb. I would be willing to bet the integrals generated now are more accurate than the original, so I re-ran them all.

Closes #13

My own todo list:

• Look through the changes
• Try running a couple of the geometries and check that the integrals I get match closely with the new reference integrals

After including the changes you recently merged I'm still getting identical output to your new references on the few files I tested. I'm not sure how to verify whether the integrals are correct but I'm working on adding a test to make it easier to tell in the future whether code changes significantly impact the integrals.

Does it make sense that the number of lines changed? I don't know so just asking. For each of the couple geometries I checked it seems like the number of lines in A shrinks by a similar factor but the number of lines in SENT and pVp remains the same.
