connects #188

This pull request makes significant changes to the key performance metrics and non-energy benefit options, primarily focusing on removing several emissions-related metrics and options, updating terminology for air quality metrics, and simplifying related keyword lists. These changes streamline the codebase and clarify the available metrics and options for both performance tracking and non-energy benefits.

Key Performance Metrics Updates

• Removed multiple emissions-related metric values from the KeyPerformanceMetricValue type, including stationary fuel, purchased energy, value chain, water pollutant, mobile fuel, process, and refrigerant emissions.
• Deleted corresponding emissions-related metric options from KeyPerformanceMetricOptions, including stationary fuel, purchased energy, value chain, water pollutant, mobile fuel, process, and refrigerant emissions. [1] [2] [3]
• Updated terminology to use "dust discharge," "particulate release," and "NOx, SOx, CO release" instead of "emissions" for relevant metrics. [1] [2] [3]
• Removed keywords associated with deleted metric values from KpmKeywords. [1] [2]

Non-Energy Benefit Options Updates

• Removed several emissions-related option values from NebOptionValue, including chemical and refrigerant gas emissions.
• Deleted corresponding NEB options for reducing refrigerant gas and chemical emissions, and removed references to deleted KPMs in other NEB options. [1] [2] [3] [4] [5]
• Updated terminology in NEB options to use "dust discharge" instead of "dust emission."

Keyword List Simplification

• Removed emission-related keywords from NEB keyword lists, including those for chemical and refrigerant gas emissions, and updated dust-related keywords to match new terminology. [1] [2] [3] [4]
