parameter ordering is inconsistent between pooling and convolution

[hobofan]

The ordering of the stride and padding is inconsistent between new_convolution_config andnew_pooling_config`, making their usage unituitive.

    fn new_pooling_config(
        &self,
        window: &[i32],
        padding: &[i32], // padding first
        stride: &[i32],
    )

    fn new_convolution_config(
        &self,
        src: &::co::tensor::SharedTensor<f32>,
        dest: &::co::tensor::SharedTensor<f32>,
        filter: &mut ::co::tensor::SharedTensor<f32>,
        stride: &[i32], // stride first
        zero_padding: &[i32],
    )

We should decide on one ordering and use that consistently.
Are there any other function signatures that could be affected by this?
