Almost done, this is a bit trickier than I thought, but there's fun in doing it.
The syntax I'm implementing is the following:

entity A
entity B

relationship OneToOne {
  A{b} to A with jpaDerivedIdentifier
}

The syntax is good I think, I will implement in https://github.com/Blackdread/sql-to-jdl as soon as this is ready in JDL.

@colameo Does the syntax look good to you?
