fn filter_input_prices(
input_prices: &CommodityPrices,
markets_to_balance: &[(CommodityID, RegionID)],
) -> CommodityPricesExpand description
Filter prices data to only include prices for markets not being balanced
Markets being balanced (i.e. with commodity balance constraints) will have prices calculated internally by the solver, so we need to remove them to prevent double-counting.
