Create new cohorts based on provenance table with unique pixelGroup and add to cohortData

plantNewCohorts(
  newPixelCohortData,
  cohortData,
  pixelGroupMap,
  currentTime,
  successionTimestep
)

Arguments

newPixelCohortData	the cohorts that were harvested
cohortData	A `data.table` with columns: `pixelGroup`, `ecoregionGroup`, `speciesCode`, and optionally `age`, `B`, `mortality`, `aNPPAct`, and `sumB`.
pixelGroupMap	A `RasterLayer` with pixel values equal to a pixel group number that corresponds exactly to `pixelGroup` column in `cohortData`.
currentTime	The current simulation time e.g., `time(sim)`.
successionTimestep	succession timestep used in the simulation

A data.table with a new cohortData
