Calculates the average (mean) of groups of consecutive items within the list.
For example, if the input list contains 6 elements and
Items per Group is 3, the output list will contain the mean of the first 3 values followed by the mean of the second 3 values.
If the input list does not divide evenly into
Items per Group, the output list will include the mean of the final partial input group as if it were a full group.
If there are no input values, the node outputs an empty list.
For point types, the node averages each component of the value.
Thanks to Martinus Magneson for developing the node this is based on.
