Add support for Vec<T> type

[karatakis]

Motivation

With sea-orm 0.10.X the Postgres databases allow to hold Vec<T> columns. With this feature we can enable Seaography to support those types.

Proposed Solutions

• Modify entity_object.rs to add support for Vec
• Modify filter_input.rs to add support for Vec
• Modify filtering.rs to add support for Vec
• Modify order_input.rs to skip this field from ordering

Additional Information

Its really complex how to order based on this field, so its better to skip it for the moment.
