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
        scored by the true skill statistic of Allouche, Tsoar and
        Kadmon (2006) <doi:10.1111/j.1365-2664.2006.01214.x>, the
        setting used for species distribution modelling from
        microclimate loggers.
