binned destroys metadata

[JaimeRZP]

Let's say that I have an instance of the Result class Cls = Result(array) where array has some metadata like array.dtype.metadata.
If we now bin Cls like Cqs = heracles.binned(Cls) and read the metadata of the arrays inside Cqs we get None

That's indeed an oversight, fixing it now.

@JaimeRZP, should we open a separate issue for moving the metadata out of array.dtype and into the Result class itself?

Many thanks!!
