> Implement canonicalization (+ fastpath aka checking if Variant is already
> canonicalized)
> This part contains only canonicalization, without wiring to expressions
> After canonicalization Variant should have
> - All dict keys sorted
> - No unused keys
> - All numeric types normalized to smallest fitting datatype (e.g.: [10 as
> int64] and [10.0 as decimal] to 10 as int8
> - float/double -0.0 converted to 0.0
> - Have all NaNs in normalised form
