prepSpeciesTable(
  speciesTable,
  speciesLayers,
  sppEquiv = NULL,
  sppEquivCol = "LandR"
)

`url`	If NULL (the default), uses one from D. Cyr's LANDIS-II files: https://github.com/dcyr/LANDIS-II_IA_generalUseFiles/master/speciesTraits.csv).
`dPath`	The destination path.
`cacheTags`	User tags to pass to `Cache`.
`speciesTable`	A raw species traits table
`speciesLayers`	stack of species layers rasters
`sppEquiv`	table with species name equivalencies between the kNN and final naming formats. See `data("sppEquivalencies_CA", "LandR")`. Only necessary if `mixedType == 2`. If not provided and `mixedType == 2`, will attempt to use `data("sppEquivalencies_CA", "LandR")`.
`sppEquivCol`	the column name to use from `sppEquiv`. Only necessary if `mixedType == 2`. If not provided and `mixedType == 2`, will attempt to use "Boreal".
