Add Avro file support for Parsons Tables

[matthewkrausse]

Introduce functionality for reading and writing Avro files in the Table class, including methods for basic operations, schema handling, and support for various compression codecs.

Looks like I am running into an issue with the limited dependencies. fastavro should be a dependency of the petl package but they are not being loaded in I guess. Wanted to chat through this before just adding fastavro to the limited dependency set which seems wrong. @austinweisgrau Have any thoughts here?

For the limited dependencies setup, you need to add the dependency in the setup.py file. You'll want to think about if it should be an "extra" (so if people want to be able to use that functionality, they need to install parsons with parsons[avro] or if it should auto-bundled with parsons for everyone, even in the friendly dependencies setup.

By default, it should probably be the former (need to opt-in with parsons[avro]).
