Stochastic/Multi-Outages: add CHP, modify outputs; CHP fixes

What's Changed

• Make outages output names not dynamic, add units to outages results, microgrid_upgrade_cost_fraction default to 0 by @hdunham in #202
• Add CHP to stochastic/multi- outages, some CHP tweaks for UI V3 by @Bill-Becker in #201
• Stochastic/Mulit-Outages: add CHP, modify outputs. Also CHP fixes. by @Bill-Becker in #205

Full Changelog: v0.28.1...v0.29.0

v0.29.0

Added

• Add CHP FuelUsed and FuelCost modeling/tracking for stochastic/multi-outages
• Add CHP outputs for stochastic/multi-outages

Changed

• Made outages output names not dynamic to allow integration into API
• Add missing units to outages results field names: unserved_load_series_kw, unserved_load_per_outage_kwh, generator_fuel_used_per_outage_gal
• Default Financial field microgrid_upgrade_cost_fraction to 0
• Add conditional logic to make CHP.min_allowable_kw 25% of max_kw if there is a conflicting relationship
• Iterate on calculating CHP heuristic size based on average heating load which is also used to set max_kw if not given: once size_class is determined, recalculate using the efficiency numbers for that size_class.

Fixed

• Fix non-handling of cost-curve/segmented techs in stochastic outages
• Fix issues with simulated_load.jl monthly heating energy input to return the heating load profile
