Bumps chalk from 2.4.2 to 3.0.0.

Sourced from chalk's releases.

v3.0.0

This release has been in development for more than a year and massively improves performance and the time it takes to import Chalk.

Thanks to @​stroncium for his hard work on this. 🙌

Breaking

• Require Node.js 8 3ef170b
• Remove the .enabled property in favor of .level (#356) 1f77953
  • Why: It was confusing to users to have two properties for detecting color support.
  • Migrate:

-if (chalk.enabled) {}
+if (chalk.level > 0) {}

• Remove chalk.constructor() in favor of chalk.Instance() (#322) de2f4cd
  • Migrate:

-new chalk.constructor({level: 1});
+new chalk.Instance({level: 1})

Minor breaking

• Use CommonJS-compatible export in TypeScript definition (#344) 98628d9
  • Why: Faking default export for TypeScript broke IntelliSense for JavaScript.
  • Migrate:

-import chalk from 'chalk';
+import chalk = require('chalk');

• Drop built-in Flow type definition d3be9c6
  • Why: None of us use Flow and we were not good at maintaining the type definition. You can get the types at flow-typed (needs to be updated to Chalk v3, open an issue on flow-typed).
• Rename the ChalkOptions TypeScript type to Options cf66156
• Remove dim style workaround for Windows (#331) cd5de7a
  • Why: The issue was fixed in newer Windows 10 builds.
• Remove the blue color workaround for Windows (#330) 2ca015c
  • Why: The issue was fixed in newer Windows 10 builds.
