      See SERVER-62940 for details. This ticket is to investigate (and potentially implement a fix) whether $avg suffers from the same issue as $sum (it is likely that this is the case given that in the case of a Decimal total for $avg, we convert the DoubleDoubleSummation to a Decimal and lose precision in the same way that $sum does)
