[Bug]: Functions do not take null named expressions into account
Description
We have found a deviation from Excel where named expressions not set are taken into account in functions. E.g. for the following code:
hf.addNamedExpression("a", "=1");
hf.addNamedExpression("b", "=1");
hf.addNamedExpression("d", null);
hf.addNamedExpression("e", "=AVERAGE(a,b,c)");
// e yields 0.666666666666667, but should yield 1
In Excel the corresponding example correctly yields 1: Hyperformula function issue.xlsx
This causes some issues, as it either requires that users of Hyperformula always define all required named expressions or they take this into account in formulas, which will give very long formulas.

Hi @jboysen! Thank you for reaching out to us. This behavior doesn't seem correct. We will fix it in one of the upcoming releases.
It seems that there is an issue with the implementation of the function AVERAGE. The non-numeric arguments passed as cell references or raw values are ignored (following the definition of AVERAGE). Named expression arguments, however, are coerced to number instead.
Other functions from NumericAggregationPlugin may also be affected by this issue.
