Description: Fits archetypal analysis models, including Euclidean,
        probabilistic, kernel, and directional variants. Methods
        include classical archetypal analysis from Cutler and Breiman
        (1994) <doi:10.1080/00401706.1994.10485840>, PCHA and kernel
        variants from Mørup and Hansen (2012)
        <doi:10.1016/j.neucom.2011.06.033>, probabilistic archetypal
        analysis from Seth and Eugster (2016)
        <doi:10.1007/s10994-015-5498-8>, directional archetypal
        analysis from Olsen et al. (2022)
        <doi:10.3389/fnins.2022.911034>, AA++ initialization from Mair
        and Sjölund (2023) <doi:10.48550/arXiv.2301.13748>,
        coreset-style initialization from Mair and Brefeld (2019)
        <https://proceedings.neurips.cc/paper_files/paper/2019/file/7f278ad602c7f47aa76d1bfc90f20263-Paper.pdf>,
        and adapted AIC from Suleman (2017)
        <doi:10.1109/FUZZ-IEEE.2017.8015385>. Provides initialization
        helpers, model selection paths, plotting methods, 'broom'
        methods, and a 'tidymodels' recipe step.
