At this moment relu_layer op doesn't allow threshold configuration, and legacy RELU op allows that.
We should add configuration option to relu_layer.

Append class to all HashCodeBuilders in Gaffer for the below issue to minimise hash collisions.

@Test
    void name() {
        Foo foo = new Foo();
        Bar bar = new Bar();

        assertFalse(foo.equals(bar));
        assertNotEquals(foo.hashCode(), bar.hashCode()); //fails
    }

    class Bar {
        int a = 3;

        @Override
        public int hashCode() {

/home/runner/work/ibis/ibis/ibis/tests/all/test_temporal.py:5: FutureWarning: pandas.util.testing is deprecated. Use the functions in the public API at pandas.testing instead.

IOW switch pandas.util.testing -> pandas.testing.
