Added support for outputs from BSM ancestral range reconstruction and the new SBEARS method.

This version includes

• New calc_sbears function to compute site-based estimation of ancestral
  range of species

• New calc_bsm function, a wrapper function used to generate realized change
  areas across the tree nodes and branches extracted from BioGeoBEARS model
  and BioGeoBEARS::runBSM()

• calc_insitu_diversification and calc_age_arrival now supports output from
  calc_bsm function

• find_max_nclust now supports parallel computation

• New plotting functions plot_age_comm, plot_ada, plot_dispersal,
  plot_evoregions and plot_insitu_diversification are provided and can be
  used directly with the outputs of most Herodotools functions
