feat: Implements ValueCurves & Improve Prime Mover and Fuel Type Mapp…

…ing (#12)

1. Implemements Value Curves for Heat Rates- Input Output Curves (linear
and quadratic) and Average value curves implemented w/ a else case for
un-implemented curves
2. Redo Prime-Mover and Fuel Type Assignment:

Specification of fuel type and prime-mover type is both done in the
`user_dict.yaml` file. These two key are used to reference the ModelMap
from the `r2x/defaults/config.json` : `generator_models` dictionary

Same read order of (1) device name map, (2) Plexos fuel name map, (3)
Inference by name mapper.

user_dict_example.yaml:
```
# Mapping of PLEXOS Generators to Sienna Fuels and PM Types
# {plexos_object: {fuel: sienna_fuel, pm_type: sienna_primemover_type}}
device_map:
    gas_plant_example_name: 
      fuel: GAS
      type: GT
# Plexos Fuel Type Mapping
# {plexos_fuel: {fuel: sienna_fuel, pm_type: sienna_pm_type}}
plexos_fuel_map: 
    Nat. Gas:
      fuel: GAS
      type: GT
    default:
      fuel: GAS
      type: OT

# Infers Fuel Type and PrimeMover
# {inference_string: {fuel: sienna_fuel, pm_type: sienna_pm_type}}
device_name_inference_map:
    wind:
