Problem with read_output() when using read_only argument

[palderman]

read_output() is reading some columns as character that should be double when using the read_only argument. To duplicate the problem, first run the standard Kansas wheat experiment KSAS8101.WHX with CERES wheat. Then read PlantGro.OUT with:

library(DSSAT)
file.copy("/DSSAT47/Wheat/KSAS8101.WHX", ".")
options(DSSAT.CSM = "/DSSAT47/dscsm047")
run_dssat("C", "KSAS8101.WHX 1")
read_output("PlantGro.OUT",  read_only = c("TRNO", "DATE", "RUN", "RUNNO", "LAID", "CWAD", "LWAD", "SWAD", "T#AD"))
