Add soil layers (by interpolation) if not already present and store in soil data input file

calc_RequestedSoilLayers(
  SFSW2_prj_meta,
  SFSW2_prj_inputs,
  runIDs_adjust,
  keep_old_depth = TRUE,
  verbose = FALSE
)

Splitting existing soil layers into two new layers will "exhaust" the values of fields “EvapCoeff”, “TranspCoeff”, and “Imperm”, i.e., sum remains constant; and will "interpolate" the values of the fields “Matricd”, “GravelContent”, “Sand”, “Clay”, “SoilTemp”.
