Renovate time series functionality for MarketBidCost

[GabrielKS]

Depends on NREL-Sienna/InfrastructureSystems.jl#367. Here we:

• Add a validation function is_market_bid_curve and factory function make_market_bid_curve to deal with market bid curves, which are CostCurve{PiecewiseIncrementalCurve}s with NaN first x-coordinate and initial input.
• Make the market bid cost time series return time arrays of these objects, even though they must be constructed with time series of FunctionData.
• Rewrite cost_function_timeseries.jl so that less logic has to be duplicated for every new field that works this way
• Make no_load_cost and start_up fields of MarketBidCost work this way

@GabrielKS we can merge and add methods as needed during the PSI integration
