* 1. loop through the list
* 2. for every element that is TRUE:
* 3. map the specific stockpile_settings index into a general material, creature, etc index
* 4. verify that type is allowed in the list (e.g., no stone in gems stockpiles)
* 5. add it to the protobuf using FuncWriteExport
*
* The unserialization process is the same in reverse.
