- the purpose of this constructor method is to generate all `Pixel`s for a `Grid` that have at least one `Address` assigned to them - fix missing `UniqueConstraint` in `Grid` class => it was not possible to create two `Grid`s with the same `.side_length` in different cities - change the `City.viewport` property into two separate `City.southwest` and `City.northeast` properties; also add `City.total_x` and `City.total_y` properties for convenience
