Publish assets with Composer hook

[driesvints]

Like laravel/horizon#554 it should also be possible for Telescope to publish updated assets after a composer dependency update. Telescope will need to add its own assets command for this.

An alternative to this could be:

• Render the assets inline (downside: no caching, loaded each request but not so big an issue because it's loaded only on the first request)
• Pass the assets through the API (eg /telescope/assets/script.js -> AssetController@getScriptJs`, which could set a TTL for browser caching)
