Description: Implements a four-stage pipeline for probabilistic seismic
        performance analysis of slopes and embankments. The package
        takes a uniform-hazard spectrum at multiple return periods as
        input (any source) and produces: (1) synthetic soil profile
        generation and fundamental period estimation from USCS
        classification via Ishihara's small-strain shear-modulus model
        and the inhomogeneous truncated shear-beam theory of Gazetas
        and Dakoulas; (2) nonlinear site amplification using the
        NGA-East ergodic site-response models (Stewart et al. (2020)
        <doi:10.1177/8755293019878185> and Hashash et al. (2020)
        <doi:10.1177/8755293019878193>, with the 2017 PEER-report
        generation retained as an option), with inter-period
        correlation via Baker & Jayaram (2008) <doi:10.1193/1.2857544>;
        (3) Monte Carlo ensemble of six empirical Newmark sliding-block
        displacement models (Ambraseys & Menu (1988)
        <doi:10.1002/eqe.4290160704>, Jibson (2007)
        <doi:10.1016/j.enggeo.2007.01.013>, Saygili & Rathje (2008)
        <doi:10.1061/(ASCE)1090-0241(2008)134:6(790)>, Bray &
        Travasarou (2007)
        <doi:10.1061/(ASCE)1090-0241(2007)133:4(381)>, Bray & Macedo
        (2017) <doi:10.1016/j.soildyn.2017.05.024>, and the Bray and
        Macedo shallow-crustal update) with coherent correlated draws;
        (4) log-log inversion to the performance-based seismic
        coefficient kmax at user-specified displacement targets. All
        outputs are 'data.table' objects.
