NACCulator prints out an Initial Z1X when running -ivp on Optional Modules regardless of visit number

[s-emerson]

This is a problem because the Z1X is a UDS form that cannot be submitted as an Initial packet type at a Follow-up UDS visit. If the visit number is >1, NACCulator should not print out an Initial Z1X (packet type I, IL, or IF).

For example, PTID 3 has their first LBD module collected at UDS visit 7. This is an Initial (IL) packet type with visit number 7.

When running NACCulator using the -lbdsv -ivp flag, it prints out an Initial LBD packet for PTID 3 visit 7.

This includes the Z1X form, since the Z1X is part of the visit in REDCap and is necessary for processing the correct forms during a NACCulator run.

In order to submit to NACC, we currently need to manually delete this extra Z1X form. It should not be printed as part of the output for any LBD or FTLD visit number that is greater than 1.
