function to translate from soil, veg, and mature age data (already in a table) to the required read-in model parameters
add_carbon_info(
data,
carbon_info_table,
matchvars = c("region", "GLU", Cdensity_LT = "Land_Type")
)
= input data tibble to receive carbon info
= table with veg and soil carbon densities, and mature.age
= a character vector for by = in left_join(data, carbon_info_table, by = ...)
the original table with carbon density info added
