Air-sdk

- Increased default read timeout for `Image` uploads

Changed
- All model `update()` calls now generate a `PATCH` request instead of `PUT` to avoid unintentional updates to the object

Added
- All API requests now include an explicit default timeout
- `publish()` and `unpublish()` methods for `Image` objects
Changed
- Improved 403 error handling

Fixed
- `AirApi.images.create()` now logs an error and still returns the `Image` object when an upload attempt fails

Added
- For sessions authenticated using a username and password, the `AirApi` client instance will now automatically try to refresh its authorization token after it expires

Added
- `AirApi.simulations.create()` now accepts an optional `topology_data` kwarg. This option is now preferred when creating a simulation from a DOT file and assigning it to an organization.
- `AirApi.topologies.create()` now logs a warning when additional kwargs are included with the `dot` kwarg. `AirApi.simulations.create()` should generally be used instead.
