added an example so pub doesn't punish us

• Added an example.

• Use QrVersions.auto and let the library pick the appropriate version for you.
• Add an image that will be overlaid in the centre of the widget. You can specify the image size but not position.
• QrImage.onError has been removed. It was horribly broken so we decided to not deprecate it and just remove it totally.
• QrImage.errorStateBuilder introduced to allow you to display an in-line Widget when an error (such as data too long) occurs. By default the error state Widget will be constrained to the QRImage bounds (aka a Square) but you can use the constrainErrorBounds property to prevent that.
• A bunch of bug fixes you can look at in the source code.

• Adds analyzer configuration
• Fixes linting issues
• Migrate to Dart 2.x friendly syntax
• Tidy some initialization logic / code
• Bump copyright

• Add image data export functions (see test/painter_tests.dart for an example)
