Support array types via the cli

Feature Request

Is your feature request related to a problem? Please describe.

SeaORM supports array types for postgres, the loco cli currently doesn't. I've been manually updating the migration files after generating sparse models. It would be nice to have the ability to generate models with array types directly via the cli.

Describe the solution you'd like

An addition of the following kind to the cli:

cargo loco generate model movies title:string actors:[string]

Where [string] can be all possible ColumnTypes
