xarray-2022.9.0 breaks weldx

[marscher]

• dimensions with just one element cannot be aligned any more with arrays having more dimensions. E.g. dims ("time", ) is not alignable to other dims ("time", "c", "foobar").
  ValueError: cannot align objects with join='exact' where index/labels/sizes are not equal along these coordinates (dimensions): 'time' ('time',)

I'm afraid that will probably require a deeper look our indexing/interpolaition code

Maybe this is a good time for a new release that forbids the new xarray version since there are no new features coming in in the near feature anyway. What do you think @marscher ?

pinning until we'll resolve this sounds the right thing to do.
