Express Normalize Query Params Middleware

Express middleware that normalizes incoming query parameter names to be case-insensitive. Current stable version is 0.5.1, with low release cadence (last update likely pre-2018). Key differentiator: simple array-based whitelist approach, no dependencies, small footprint. Alternative to libraries like 'express-case-sensitive' or manual normalization. Note: only handles case normalization, not type coercion or default values.
