nutrient_efficiency_block

Internal helper that calculates retention, excretion, and growth efficiencies
from raw flux values. Used by <code>calculate_nutrient_efficiencies()</code> to
avoid duplicating the identical calculation for nitrogen and phosphorus.

An implementation of the 'Fish Bioenergetics 4.0' framework
described in Deslauriers et al. (2017)
<doi:10.1080/03632415.2017.1377558>. Provides automated parameter
optimization, multi-prey diet modeling, and comprehensive energy budget
simulations for fisheries research and aquaculture applications. An
optional 'TMB' (Template Model Builder) backend delivers 10-50x speedup
in maximum likelihood estimation while maintaining full backward
compatibility. Includes species-specific parameter databases and tools
for modeling fish growth, consumption, and metabolism under varying
environmental conditions.
