Is your feature request related to a problem?

I was trying to make a simple operation for two DataArrays: applying the * operation along a single common dimension, but I couldn't find any simple and straight-forward way to apply it. This is a problem that can be faced very often when having weights to apply to a Dataset/DataArray, as in this example.

Describe the solution you'd like

I believe a very useful implementation would be adding xr.mult(*arrays, dim, *args) - or xr.prod or similar -, exactly as it is for the xr.dot(*arrays, dim, *args), but instead of applying the @ product it would apply the * product.

Describe alternatives you've considered
