AttributeError in AreaFill.deserialize_model when fetching LineChart with custom-area-fills (v2.0.6+)

[marcelpauly]

Starting with version 2.0.6, get_chart() fails with an AttributeError when fetching a LineChart that has custom area fills enabled. The error occurs in AreaFill.deserialize_model(), which expects custom-area-fills to be a dictionary but receives a list instead. When custom area fills are disabled via the Datawrapper web interface, get_chart() works fine even with v2.0.6+.

Thank you for maintaining this excellent library! Please let me know if you need any additional information.
