Support new deployment statuses

👋 First of all, thanks for the project.

Issue

I saw that the gem doesn't support the deployment statuses: in_progress or queued.

The reason is because instead of sending 'application/vnd.github.cannonball-preview+json', they require application/vnd.github.flash-preview+json in the Accept header for these statuses while are in beta.

Tests

I checked that using application/vnd.github.flash-preview+json in all deployments requests made (list N deployments, get a status from a deployment, ...) worked like a charm. I assume that's the only change it needs.
