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.
