Postgres field extension - inet data type
```python
class SomeField(Field):
    field_type = 'inet'
```

If you require conversion from python data-types to db-friendly data-types, you would implement `python_value()` and `db_value()` as needed.

First off, Peewee is great :)

Postgres supports network data types.

What would be the best way to implement support for these fields instead of peewees IPAddr field?

A simple Field extension with the right type would suffice?

If so, I will prototype it and open a PR
