Set or get the reset filter handler. The reset filter handler is a function that resets the
chart's filter list by returning a new list. Using a custom reset filter handler allows you to
change the way filters are reset, or perform additional work when resetting the filters,
e.g. when using a filter server other than crossfilter.

The handler should return a new or modified array as the result.
@example
// default remove filter handler
function (filters) {
    return [];
}

// custom filter handler (no-op)
chart.resetFilterHandler(function(filters) {
    return filters;
});
@param {Function} [resetFilterHandler]
@returns {BaseMixin}
