Add CustomType to the Specification Go Bindings

[bendbennett]

Currently, an Object is a []ObjectAttributeType when obtained from the Specification Go bindings and has the following form:

type ObjectAttributeType struct {
    Name string `json:"name"`

    Bool    *BoolType            `json:"bool,omitempty"`
    Float64 *Float64Type         `json:"float64,omitempty"`
    Int64   *Int64Type           `json:"int64,omitempty"`
    List    *ListType            `json:"list,omitempty"`
    Map     *MapType             `json:"map,omitempty"`
    Number  *NumberType          `json:"number,omitempty"`
    Object  ObjectAttributeTypes `json:"object,omitempty"`
    Set     *SetType             `json:"set,omitempty"`
    String  *StringType          `json:"string,omitempty"`
}

This type needs to be extended to include CustomType *CustomType.

This will require a breaking change, but the specification should certainly allow this customization. 👍 Better now than later.
