Support for composite keys

[ajozwik]

Quill does not support query on Embedded class. See StatementInterpolator.scala

          s"    run(query[Users].update(_.embeddedCaseClass -> lift(someInstance)))\n" +
          s"  In that case, make sure you are updating individual columns, for example:\n" +
          s"    run(query[Users].update(\n" +
          s"       _.embeddedCaseClass.a -> lift(someInstance.a),\n" +
          s"       _.embeddedCaseClass.b -> lift(someInstance.b)\n" +
          s"    ))"

At least simple support for Embedded composite key with two arguments is needed.
