hsquared: 'R' Interface for 'Julia'-Backed Quantitative-Genetic Models

Provides an interface for quantitative-genetic models in 'R', backed by the 'HSquared.jl' engine for 'Julia'. Fits Gaussian pedigree animal models by restricted maximum likelihood, using average-information restricted maximum likelihood (AI-REML; Gilmour et al. (1995) <doi:10.2307/2533274>) for the univariate model. Returns heritability, variance components, breeding values, and covariance and correlation matrices for multivariate models. Formula and pedigree validation can run without 'Julia'. Model fitting requires a local 'Julia' and 'HSquared.jl'; use hs_control(engine = "validate") to preview the model contract without fitting. What you may report is listed on the package article 'Can I fit and report this?', not in validation_status(), which is a developer evidence table. Model-specific restrictions are documented in that article. Uncertainty intervals are not coverage-calibrated.
