Custom keys mapping between struct and json

[Mehonoshin]

Hey, folks!

I wonder if it is possible to implement some custom mapping of keys?

E.g. I have a json
{"a": 1, "b": 2} and I want to decode it to defstruct key_one: '', key_two: ''

Do you think it is possible to implement such behavior within your library?
I can do that if you approve that it is suitable for your project.

@devinus WDYT?

I'd love to have this, so our JSON can use camelCase keys, and our elixir can stay in snake_case
