pub fn get_default_alpha(regularization: u8) -> (f32, f32)Expand description
Get default alpha values based on regularization level (1-4)
Matches Julia QuantitativeSusceptibilityMappingTGV.jl reference:
alpha = [0.001, 0.001] + [0.001, 0.002] * (regularization - 1)
Level 2 (default) gives α₀=0.002, α₁=0.003
