Include a curated list of resources

It would be neat to include links to benchmarks, articles, and papers.

Ideas:

• There were a couple of academic papers recently on user@ that compared Avro to a variety of JSON binary formats.
• IntelliJ Avro IDL schema support: https://plugins.jetbrains.com/plugin/15728-apache-avro-idl-schema-support
