Beam intersections references

The “Beam intersections references” option has been added to the “Groups” menu of the “Beam definition” and “Results” tabs. These references can now be generated automatically according to the order of the frames.

For jobs created from version 2023.a onwards, this will be the default option. For jobs that have already been created, the order in which they were generated is maintained, but the "Beam intersections references" option can be used to change the order.
