This PR improves the typing of align.
Before: the type of the inputs was reduced to the common superclass and the return type was the same. This often required casts or ignores when mixing classes (e.g.
da, ds = xr.align(da, ds)
.Now: the return types are exactly the same as the input types if the number of passed arguments is <=5.
Only downside: it requires some ugly overloads with type ignores on align. Maybe someone knows how to type this better?
