Original: [coeff_array] → [concatenated_significance_maps + nonzero_values]
Concatenated Maps Layout:
[Y_map][Co_map][Cg_map][Y_vals][Co_vals][Cg_vals]
[Y_map][Co_map][Cg_map][Y_vals][Co_vals][Cg_vals] (channel layout 0)
[Y_map][Y_vals] (channel layout 1)
[Y_map][Co_map][Cg_map][A_map][Y_vals][Co_vals][Cg_vals][A_map] (channel layout 2)

(replace Y->I, Co->Ct, Cg->Cp for ICtCp colour space)
- Significance map: 1 bit per coefficient (0=zero, 1=non-zero)
- Value arrays: Only non-zero coefficients in sequence per channel
