Master not up to date with latest published version

[Frank3K]

On pub.dev version 1.0.1 is available: https://pub.dev/packages/qr_code_scanner/changelog. However, currently on master, the pubspec.yaml and CHANGELOG.md still point to 1.0.0.

I also observer differences in kotlin source files, e.g. QRView.kt which does not include the CameraInfo enum, which the published 1.0.1 version does use.
