Add support for json.Number. (#414)

This commit adds support for encoding json.Number as a number
instead of as a string, which is the underlying type of
json.Number.

Care has been taken to not introduce a dependency on the
encoding/json package, by using an interface that specifies the
methods of json.Number instead of the datatype itself. This also
means that other packages that use a similar datatype will be
supported. (Like json-iterator)

This is useful for tools that wish to convert JSON data into YAML
data by deserializing JSON into a map[string]interface{}, and use
the json.Encoder's UseNumber() method, or structs that use the
json.Number datatype and also wish to support yaml.
