process_predator_energy_data

Ensures <code>ED_data</code> is available as a numeric vector of length
<code>n_days + 1</code>. Accepts either a pre-built vector via <code>ED_data</code>
or a pair of scalars via <code>ED_ini</code>/<code>ED_end</code> (which are linearly
interpolated to produce the full vector internally).

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.
