calmet_03_output_opts: Set CALMET parameters for the output options
In rich-iannone/PuffR: A set of tools to help with CALPUFF dispersion modelling.

This function validates and writes CALMET parameters for the output options to the working CALMET.INP file.

`calmet_inp`	the absolute path and filename for the working CALMET input file.
`lsave`	save meteorological fields in an unformatted output file.
`iformo`	type of unformatted output file: (1) CALPUFF/CALGRID type file [CALMET.DAT], (2) MESOPUFF-II type file [PACOUT.DAT].
`lprint`	whether to print meteorological fields in the iuvout, iwout, and itout options.
`iprinf`	print interval in hours.
`iuvout`	specification of which layers of U,V wind component to print; vector must be the same length as the number of levels (nz).
`iwout`	specification of which layers of the W wind component to print; vector must be the same length as the number of levels (nz).
`itout`	specification of which levels of the 3D temperature field to print; vector must be the same length as the number of levels (nz).
`stability`	whether to print the PGT stability class (will only print if lprint is TRUE).
`ustar`	whether to print the friction velocity (will only print if lprint is TRUE).
`monin`	whether to print the Monin-Obukhov length (will only print if lprint is TRUE).
`mixht`	whether to print the mixing height (will only print if lprint is TRUE).
`wstar`	whether to print the convective velocity scale (will only print if lprint is TRUE).
`precip`	whether to print the precipitation rate (will only print if lprint is TRUE).
`sensheat`	whether to print the sensible heat flux (will only print if lprint is TRUE).
`convzi`	whether to print the convective mixing height (will only print if lprint is TRUE).
`ldb`	whether to print input meteorological data and internal variables.
`nn1`	if ldb is TRUE, the first time step for which debug data are printed.
`nn2`	if ldb is TRUE, the last time step for which debug data are printed.
`ldbcst`	whether to print distance to land internal variables (output will be a .GRD file DCST.GRD).
`ioutd`	whether to print the test/debug wind fields to disk files.
`nzprn2`	number of levels, starting at the surface, to print.
`ipr0`	print the interpolated wind components?
`ipr1`	print the terrain-adjusted surface wind components?
`ipr2`	print the smoothed wind components and the initial divergence fields?
`ipr3`	print the final wind speed and direction fields?
`ipr4`	print the final divergence fields?
`ipr5`	print the winds after kinematic effects are added?
`ipr6`	print the winds after the Froude number adjustment is made?
`ipr7`	print the winds after slope flows are added?
`ipr8`	print the final wind field components?
