Amazon Ion support (and/or other JSON superset)

[Páll Haraldsson]

I just discovered Amazon Ion. It's both a JSON superset and binary JSON. I do not see that Julia supports it.

Maybe supporting it belongs in another package, this one doesn't have any binary support. I know of BSON.jl.

Since Ion is a superset, possibly this package should support it, the non-binary part (as non-default option?)?

Is Arrow possibly the future, and this Ion not important?

There's also YAML.jl, another JSON superset, I suppose that package much slower (but less important to be fast) for it or JSON...
