Update to readme (was listing older versions)

No functional changes.

Upgrade for Laravel 9

Issue #7 upgrade for Laravel 9

New 'root' config option for issue #3

This should not break anything. It retains support for an old config bug (driverOptions being passed into prefix in the Azure driver) where a string has been set here. That will be revisiting at some point.

Added tests

The requirement for consilience/flysystem-azure-file-storage has been raised to 0.1.1, as that version fixes some of the exceptions that the tests here look for.

Mor details in readme

0.1.1

More readme details.

First release

Still under development (more documentation and tests to add) but functional enough to use.
