• v0.53.0: GHP Options; PV, Battery, Existing HVAC Costs REopt.jl#501

This pull request introduces several updates across multiple areas, including new financial constraints, enhancements to photovoltaic (PV) inputs and outputs, and changes to the Ground Heat Pump (GHP) and Electric Storage models. It also includes updates to the API endpoints and the project's dependencies. Below is a summary of the most important changes grouped by theme.

Financial Constraints and Outputs:

• Added new financial inputs: min_initial_capital_costs_before_incentives and max_initial_capital_costs_before_incentives to define bounds for upfront capital costs. [1] [2]
• Added financial outputs: initial_capital_costs_after_incentives_bau and lifecycle_capital_costs_bau for BAU technologies such as ExistingBoiler and ExistingChiller.

Photovoltaic (PV) Enhancements:

• Added new PV inputs (size_class, installed_cost_per_kw, om_cost_per_kw) and outputs (installed_cost_per_kw, om_cost_per_kw) to improve PV cost modeling. [1] [2] [3]
• Introduced a new API endpoint /pv_cost_defaults for retrieving PV cost parameters based on input data. [1] [2]

Ground Heat Pump (GHP) Updates:

• Added new GHP inputs: load_served_by_ghp, max_number_of_boreholes, and max_ton to provide more detailed control over GHP constraints.

Electric Storage Updates:

• Introduced new electric storage inputs such as cost_constant_replacement_year, installed_cost_constant, and replace_cost_constant. Updated default values for installed_cost_per_kw and installed_cost_per_kwh. [1] [2] [3]

Dependency and Version Updates:

• Updated the REopt dependency in Manifest.toml to version 0.52.0 and linked it to the develop branch of the repository.
