Passing multiple indexes:

```python midx1 = pd.MultiIndex.from_product([["a", "b"], [1, 2]], names=("one", "two")) midx2 = pd.MultiIndex.from_product([["c", "d"], [3, 4]], names=("three", "four"))

indexes1 = wrap_pandas_multiindex(midx1, "x") indexes2 = wrap_pandas_multiindex(midx2, "y")

indexes = Indexes( indexes=dict(indexes1, indexes2), variables=dict(indexes1.variables, indexes2.variables) )

ds = xr.Dataset(indexes=indexes)

<xarray.Dataset>

Dimensions: (x: 4, y: 4)

Coordinates:

* x (x) object MultiIndex

* one (x) object 'a' 'a' 'b' 'b'

* two (x) int64 1 2 1 2

* y (y) object MultiIndex

* three (y) object 'c' 'c' 'd' 'd'

* four (y) int64 3 4 3 4

Data variables:

empty

```

That's not looking super nice, but probably we can add some convenience function or Indexes method.
