small side note for a first-time reader of this the divide-by-zero checks are a little confusing, because I expected the if statements to do something different in the case of div/0 but they are actually doing the normal flow in case of !div/0. not a big deal though

Make sure we leave the mean at 0 for Nan sums in histograms. This can happen when using the Prometheus receiver. This mirrors behavior in google prometheus-engine. Also, avoid divide by zero in exponential histograms.
