Add option to create types that include table relations

[BoilerTom90]

A nice option to this tool would be the ability to have types or interfaces generated that reflect relationships between tables.
For example, if I have a table of School, and each school can have zero or more Coaches, it would be great if the type generated for the Schools could reflect that relationship as follows:

export type Coach {
// all the fields for a coach
}
export type SchoolWithRelations {
// other fields for a School
coaches: Coach[]
}

I'm not sure if this is even possible, or how difficult it would be... but, thought I'd throw it out there.
