CLI release

Updated test runner with latest version of NoSqlMigrator library.

Also added new icon.

CLI release

I updated the NoSqlMigrator package:

• Now uses .netstandard2.0 (should have done this from the start)
• Upgraded couchbasenetclient to 3.4.8 (latest at the time)
• Fixed issue that was preventing abstract base classes for migration classes (discovered while dogfooding with Conduit project)

I didn't make any substantial changes to the CLI itself, but I thought I would do a release, just in case .netstandard2.0 change would be an issue.

Upgraded to .NET 7 and latest Couchbase SDK

I need to get a handle on the .NET versions: I would like this runner to work for .NET 5 and above. But this works for now.

Also needed to upgrade to latest Couchbase SDK.

Initial release of the command line runner

Created an initial standalone CLI runner.

Try NoSqlMigrator.Runner.exe help to see how to use it.
