v8.0.0

Breaking

• Require Node.js 12 cde5c79
• Removed deprecated url option
• The app option now accepts an object instead of a string/array:

 await open('https://sindresorhus.com', {
-	app: 'firefox'
+	app: {name: 'firefox'}
 });

 await open('https://sindresorhus.com', {
-	app: ['chrome', '--incognito']
+	app: {name: 'google chrome', arguments: '--incognito'}
 });

Improvements

• Add open.apps constants, which lets easily open Chrome and Firefox without cross-platform issues
