Description: Calculate travel time across a landscape from a set of
        user-specified locations, over a friction surface describing
        the time taken to cross each cell. Implements the least-cost
        travel time approach of Weiss et al. (2018)
        <doi:10.1038/nature25181> and Weiss et al. (2020)
        <doi:10.1038/s41591-020-1059-1>, and provides convenient access
        to their global walking and motorised friction surfaces via the
        'malariaAtlas' package. Travel times are computed with 'terra'.
        See Ryan et al. (2025) <doi:10.12688/gatesopenres.16356.1> for
        further details.
