Description: Fits and compares representations of time-varying data
        against a prediction target. Given a table of targets and a
        table of time-stamped series belonging to them, it builds each
        candidate representation, from the record unreduced through a
        calendar grain such as a week or a month to a lookback anchored
        on each target, fits the requested learners on each, scores
        every candidate on one set of held-out folds, and stacks the
        out-of-fold predictions into an ensemble. Calendar-aware
        binning keeps a bin a real week or month rather than a fixed
        block of hours. Learners, response heads and metrics are
        registered rather than hard-coded, so adding one is a
        registration and not a fork of the fitting code. The penalised
        baseline is an elastic net fitted by cyclic coordinate descent
        along a warm-started path, following Friedman, Hastie and
        Tibshirani (2010) <doi:10.18637/jss.v033.i01>. The shipped
        default is presence-absence with a joint multi-label head, the
        setting used for species distribution modelling from
        microclimate loggers, scored by the area under the ROC curve
        with the true skill statistic of Allouche, Tsoar and Kadmon
        (2006) <doi:10.1111/j.1365-2664.2006.01214.x> beside it.
