Add IOP sections to ADOE template/vignette

[manciniedoardo]

Background Information

Once test IOP data is created (#259) it would be good to showcase how to map it in the ADOE template and vignette. Pre-dose records should be mapped to "FIOPR"/"SIOPR" and post-dose ones to "FIOPPO"/"SIOPPO".

Special care should be taken to ensure rest of template/vignette makes sense also for these new records.

Often the IOP difference pre/post-dose is interesting. This can be calculated as a new computed parameter with PARAMCD = "SIOPPRPO" or "FIOPPRPO". We can use a call to derive_param_computed() for this.

Definition of Done

• ADOE vignette updated for IOP record mapping and computed parameter calculation.
• ADOE template updated for IOP record mapping and treatment, and computed parameter calculation.
