Description: Performs 'BTLLasso' as described by Schauberger and Tutz
        (2019) <doi:10.18637/jss.v088.i09> and Schauberger and Tutz
        (2017) <doi:10.1177/1471082X17693086>. BTLLasso is a method to
        include different types of variables in paired comparison
        models and, therefore, to allow for heterogeneity between
        subjects. Variables can be subject-specific, object-specific
        and subject-object-specific and can have an influence on the
        attractiveness/strength of the objects. Suitable L1 penalty
        terms are used to cluster certain effects and to reduce the
        complexity of the models.
