make_halk

This function creates a hierarchically nested age-length key that can be
used to estimate age of an organism based on proportion of sampled organisms
in each age group.

Provides methods for implementing hierarchical age length keys
to estimate fish ages from lengths using data borrowing. Users can create
hierarchical age length keys and use them to assign ages given length.
