Description: Provides generalized L-moments estimation methods for the
    generalized extreme value ('GEV') distribution. Implements both stationary
    'GEV' and non-stationary 'GEV11' models where location and scale parameters
    vary with time. Includes various penalty functions ('Martins'-'Stedinger',
    Park, Cannon, 'Coles'-Dixon) for shape parameter regularization.
    Also provides model averaging estimation ('ma.gev') that combines MLE and
    L-moment methods with multiple weighting schemes for robust high quantile
    estimation. The 'GLME' methodology is described in Shin et al. (2025a)
    <doi:10.48550/arXiv.2512.20385>. The non-stationary L-moment method
    is based on Shin et al. (2025b) <doi:10.1007/s42952-025-00325-3>.
    The model averaging method is described in Shin et al. (2026)
    <doi:10.1007/s00477-025-03167-x>.
    See also 'Hosking' (1990) <doi:10.1111/j.2517-6161.1990.tb01775.x> for
    L-moments theory and 'Martins' and 'Stedinger' (2000)
    <doi:10.1029/1999WR900330> for penalized likelihood methods.
