    [reconcile-report] upgrade calculated-cells

commit 93dd19e98bb10e2277fab17a5bf2cb6d5a2bb328

    [trep-engine.scm] upgrade engine to improve calculated-cells handling
    
    calculated-cells was formerly a vector of RHS info - heading,
    calculator-fn, subtotal? etc.
    
    This upgrades it so that calculator-fn now accepts two arguments -
    split and transaction-row? which is a bool. It uses a basic record
    with version and list-of-cells, and each cell is a record (instead of
    a vector) with relevant members.
    
    This also enables the engine to handle previous calculated-cells --
    note the income-gst-statement.scm will offer the previous one and will
    be transparently upgraded to the above -- see the function
    upgrade-to-calculated-cells-v2
