This PR implements the fitted version of the superposition of atomic potentials guess (#564), which only requires three-center two-electron integrals.
Things that are still missing:
-Z, the negative of the nuclear charge. Then, before the integrals are calculated, the coefficientsc_pjust have to be multiplied with(\alpha_p / pi)^{3/2}so that the density primitives are normalized.
