UNIQUE constraint

[Zer0xxxx]

Hello!
First of all, thank you a lot for this fp ORM.

I would like to know if it is planned to add a .unique() composite function in Orange ORM.

Like:

related_xxx_id BIGINT UNIQUE NOT NULL,

Adding constraints to the sql only makes sense if Orange can create sql migrations. And it does not per se.
However, I am considering adding a sql cli command for generating the entire db schema. When that happens, it also makes sense adding a unique() constraint.

It would be fantastic to generate the DB schema from the Orange map!
