Fire perimeter spread rate and fireline intensity — calculates spread rate normal to the elliptical fire perimeter and Byram's fireline intensity. Migrated from WildlandFire.jl@126976f2508ceacca6c486b21ae6da5b168c6f46:src/fire_spread_direction.jl:264 (`FirePerimeterSpread` @component). Algebraic-only: R_H, f, g, h, γ, H_A are inputs (parameters); cos_θ, sin_θ, θ, R_ψ, ψ, I_B are algebraic outputs.
