v0.7.0

• Improved cli experience with better logging and progress indicators.

• Removed --ssr and --flutter cli options.

• Added support jaspr config section in pubspec.yaml.

  It is now possible to define certain configuration options for the jaspr cli
  directly inside the pubspec.yaml file under the jaspr section.
  Initially supported options are:

  jaspr:
    uses-ssr: true # or false; Toggles server-side-rendering on or off.
    uses-flutter: true # or false; Whether the project uses flutter element embedding.
