Updated EPiServer.ImageLibrary.ImageSharp dependency to 1.0.1 which contains a vulnerability fix.

Fixed an issue that prevented the loading of an object as a PropertyBag. This issue occurred when a type with an enum property was stored in DDS and then later was no longer present. The missing missing enum value should have returned as an int but the load failed System.ArgumentNullException: Value cannot be null. (Parameter 'key').

Fixed an issue that redirected you to an existing URL even when you entered a non-existent URL (which should produce an HTTP 404).

Fixed an issue with a secondary exception in DefaultDataExporter.Export which caused code cleanup to occur before logging the issue. The code cleanup could result in an error, and no issue would be logged. Now, the issue is logged before code cleanup starts.
