TypeError: views_aggregator_average() after update

Problem/Motivation

A) TypeError: views_aggregator_average(): Argument #3 ($precision_group) must be of type ?int, string given, called in /***/web/modules/contrib/views_aggregator/src/Plugin/views/style/Table.php on line 559 in views_aggregator_average() (line 180 of /***/web/modules/contrib/views_aggregator/views_aggregator_functions.inc).

B) TypeError: number_format(): Argument #1 ($num) must be of type float, string given in number_format() (line 867 of /***/web/modules/contrib/views_aggregator/src/Plugin/views/style/Table.php).

Steps to reproduce

1) Create a view with display of views aggregation table
2) add a custom field
3) adjust the table settings for the field by setting column/group aggregation to "average" and parameter = 2

API changes

Change the input arguments for views_aggregator_average from ?int to ?string and cast them to int in the function. This adjustment matches the pattern of the other aggregator functions that are called from Table::executeAggregationFunctions().

The secondary issue was with the number_format function requiring a float value, which I applied a temporary fix and I haven't found what was changed to make $new_value no longer valid
