Is your feature request related to a problem?

Shall we support opt_einsum as an optional backend for xr.dot?

opt_einsum.contract is a drop-in replacement for np.einsum so this monkey-patch works today xr.core.duck_array_ops.einsum = opt_einsum.contract

Describe the solution you'd like

Add a backend kwarg with options "numpy" and "opt_einsum", with the default being "numpy"

Describe alternatives you've considered

We could create a new package but it seems a bit silly.
