As per insist of @aradi, I'm chopping the existing mega-pull-request up into coherent pieces. This one is the SAP guess from 10.1063/5.0004046. It's not supposed to solve any existing problem, but is just a nice thing to have in the XXIst century. I've also taken the liberty to make it the default guess now, or rather the only guess; please tell me if you object.

Two files in the tests had to be regenerated (B3LYP N-N and N-C) because there was some minor difference in the trailing numbers, nothing substantial AFAICS. All other tests passed right away.

For backward compatibility the old guess should still be available (and so also with its original tests) in addition to the SAP option.
