Strange map serialization with enum class keys

[9241304]

I found issue #14.
I got the same behavior for enum class keys

If I'm using numeric keys, I see this output:
{ "infos": { "1": "3.0.0", "2": "3.0.0" } }

If I'm using enum class as key, then:
{ "infos": [ [ "main", "3.0.0" ], [ "none", "3.0.0" ] ] }

Please fix this issue if possible

Hi @9241304 ,

I take it that the expected behaviour is for this to be treated like a normal map?

I'm pretty sure this can be easily fixed, thanks for pointing it out.
