PRELIM model update requires update to OPEM's product slate format

[rosewangrmi]

There is a new PRELIM version which creates a product slate in a slightly different format from the previous version that OPEM uses for inputs.

Main changes mentioned from Adrienne are:

In the old PRELIM output (all current OPEM product slate format):

1. In the product slate, for some reason Surplus NCR H2 is not listed under the volume flow bbl, but it is for energy flow and mass flow.
2. Sulpher is only represented in the mass flow, but not the volume or energy flow.
3. In volume flow bbl, the label for Surplus RFG is Surplus Refinery Fuel Gas (RFG), but it is Surplus RFG for energy flow and mass flow.

Refining team confirmed that Sulphur makes sense to only be in mass section
