Create Data Fix to migrate CUS records to new spar

[franTarkenton]

The original data migration that moved the original spar data from the dbp01 database to the new spar postgres database only moved the A class seedlots from tested parent trees.

This ticket will create a data patch that will copy the A class records that are from Custom Seedlots (CUS).

Acceptance Criteria

• Migration script is created
• Migration script added to the nr-fsa-scripts repository
• Scripts have been tested and verified against the local dev env
• Test queries are defined to verify that the script completed successfully
