Make `Reactant.RArray` a subtype of `DenseVector`

[albertomercurio]

I have noticed that the Reactant.RArray is not a subtype of a DenseVector

julia> supertypes(typeof(dx))
(ConcretePJRTArray{Float64, 1, 1, Reactant.Sharding.ShardInfo{Reactant.Sharding.NoSharding, Nothing}}, Reactant.AbstractConcreteArray{Float64, 1}, Reactant.RArray{Float64, 1}, AbstractVector{Float64}, Any)

Is there a reason for this?

It would help a lot in the implementation of generic methods to have it as a subtype of DenseVector.

we actually talked about this at the weekly meeting the other day, and this is a good idea!

want to give it a go?

I’m not familiar with the structure of this package, but I’d be happy to give it a try if you could provide some directions.
