Market bid cost with pwl cost curve

[purboday]

1. In src/devices_models/devices/common/objective_function/market_bid.jl added function _add_vom_cost_to_objective!.
2. Updated "Test Thermal Generation MarketBidCost models" in test/test_device_thermal_generation_constructors.jl to make fixed_market_bid_cost run and pass.
3. Other diffs caused by the formatter.

This file is useful but it shouldn't be checked out into the repo. I'd like the original test to be fixed.
