dependency :erlavro is using Rebar 2, which is no longer maintained and no longer works in recent Erlang/OTP versions. Remove the :manager option or set it to :rebar3 instead

I get this warning when using this package

I'm curious though, would you be fine with me making erlavro an optional dependency in addition to updating it? JSON is required, but we (and likely others) use this library without Avro and that would avoid bringing in extra dependencies (and for what it's worth I think we even got a build failure from one of them that we had to work around)

I have a simple Avro schema for testing

{ "type": "record", "name": "Exampleschema", "fields": [ {"name": "example", "type": "string"} ] }

and starting Cloudevents with

Cloudevents.start_link([{:confluent_schema_registry_url, "http://schema-registry:8081"}, {:avro_schemas_path, "./priv/schemas"}, {:avro_event_schema_name, "Exampleschema"}])

The schema-registry is reachable through docker, and my schema lives in ./priv/schemas/Exampleschema.avsc

I copied over the event from one of your examples to make sure I'm not missing anything

event = Cloudevents.from_map!(%{specversion: "1.0",type: "some-type",source: "some-source",id: "1",data: %{"example" => "bar"}})                            
%Cloudevents.Format.V_1_0.Event{ 
  data: %{"example" => "bar"},
  datacontenttype: "application/json",
  dataschema: nil,
  extensions: %{},
  id: "1",
  source: "some-source",
  specversion: "1.0",
  subject: nil,
  time: nil,
  type: "some-type"
}

when i try to encode it with avro, I get the following

event |> Cloudevents.to_avro                                                                                                                                    
[debug] reading schema `Exampleschema` from the file ./priv/schemas/Exampleschema.avsc
[debug] new schema `Exampleschema` stored with global id `121`
{:error,
 %ErlangError{
   original: {:"$avro_encode_error", :required_field_missed,
    [record: "Exampleschema", field: "example"]}
 }}

but the field is there in the data map.
