laa_data: Example length-at-age data

Description

Simple age-structured population data with age and length records for each individual. laa_data represents a well-sampled age-length dataset, whereas laa_data_low_n is one with few total samples, laa_data_low_age_n is one with few samples in some ages, and laa_data_few_ages is a dataset with few age groups sampled. Species specific datasets are similar, but with the prefix laa_ replaced by spp_. These datasets contain species specific length-at-age data
