Lite version without sqflite package

[781flyingdutchman]

If you don't use the sqflite package in your app, and you don't use SqlitePersistentStorage for the persistent storage needs of the downloader (by default it doesn't), then consider using branch V7-lite of the background_downloader repo.

The lite version is the same as the latest V7.x.x version, but without any reference to the sqflite package, so that the SQLite binaries are excluded from the Android and iOS runtime, leading to a smaller bundle size.

To use the V7-lite version, change your pubspec.yaml entry to:

background_downloader:
    git:
      url: https://github.com/781flyingdutchman/background_downloader.git
      ref: V7-lite

SqlitePersistentStorage has moved out of the background_downloader into a separate package background_downloader_sql which is a small extension package with the sqflite dependency, so you need to add this to your pubspec.yaml alongside background_downloader. The reason is that sqflite adds quite a bit of size to an app, and the default downloader does not require it, so it adds overhead for many, to benefit only those who use SqlitePersistentStorage.

Because of this change, there is no need for a Lite version of V8 (as that is now effectively the default).
