Example for slices about avro

[nrwiersma]

You only need to register types with Register for a union type, so it knows what the type looks like.

It looks like the issue you are having is that schema does not contain an array. I suggest you read the spec to fully understand schemas.

This is the correct schema and code:

type SimpleRecord struct {
		A int64  `avro:"a"`
		B string `avro:"b"`
	}

	schema, err := avro.Parse(`{"type": "array", "items":
{
    "type": "record",
    "name": "simple",
    "namespace": "org.hamba.avro",
    "fields" : [
        {"name": "a", "type": "long"},
        {"name": "b", "type": "string"}
    ]
}}`)
	if err != nil {
		log.Fatal(err)
	}

	in := []SimpleRecord{{A: 27, B: "foo"}}

	data, err := avro.Marshal(schema, in)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(data)
	// Outputs: [1 10 54 6 102 111 111 0]

	out := []SimpleRecord{}
	err = avro.Unmarshal(schema, data, &out)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(out)
	// Outputs: [{27 foo}]

I think this is worth to be added on documentation.. Probably many people will work with slices and they will have the same issue.
