rename fields from JSON deserialization

[zoechi]

I have to deserialize JSON that contains case as field name which is a reserved word in Dart and therefore I can't use that as field name in a built_value class.

Is a custom serializer like explained in #134 (comment) a possible approach to solve that, or is there something better?

It should work to rename fields using a serializer plugin, as in this request to support renaming enum values:

#144

Please let me know if that works. It would make sense to have standard plugins for doing this be part of built_value.

[zoechi]

Great! Yes, a standard way would be great.
Perhaps some field decorator and a way to get it's value during deserialization.
I'll try the custom serializer for now.

[zoechi]

I created a plugin for that and it's working fine.
Not even sure anymore if it really needs a standard plugin. Perhaps a plugin example, like the one from #144 would be enough.

[davidmorgan]

Thanks! Probably we need at least a set of examples, yes. I'll leave this issue open for that.

I'm going to merge into #144.
