Description: Implements bivariate and Multivariate Quantile-on-Quantile
    Granger causality tests building on the Quantile-on-Quantile
    regression framework of Sim and Zhou (2015)
    <doi:10.1016/j.jbankfin.2015.01.013> and the quantile Granger
    causality test of Troster (2018)
    <doi:10.1080/07474938.2016.1172400>. The bivariate test estimates
    the local-linear slope in the quantile regression of y_t on lagged
    x_t with lagged y_t as control, using Gaussian kernel weights, and
    tests it against zero by paired bootstrap. The multivariate
    (conditional) test additionally conditions on a set of moderators Z
    and optional x times Z interaction terms, in the spirit of Sinha,
    Ghosh, Hussain, Nguyen and Das (2023)
    <doi:10.1016/j.eneco.2023.107021>. A Sup-Wald summary across the
    quantile grid is also provided. Heatmaps and 3D surfaces default to
    the 'MATLAB' 'Parula' colour map.
