Calculate vapour pressure deficit and save output to a netCDF file.

nc_vpd(
  filename,
  Tg,
  vap,
  lat = NULL,
  lon = NULL,
  cpus = 2,
  overwrite = TRUE,
  output_filename = NULL
)

`filename`	String with the output filename (.nc).
`Tg`	3D structure with mean daytime temperature values.
`vap`	3D structure with vapour data.
`lat`	List with latitude `data` and variable `id`.
`lon`	List with longitude `data` and variable `id`.
`cpus`	Number of CPUs to use for the computation.
`overwrite`	Boolean flag to indicate if the output file should be overwritten (if it exists).
`output_filename`	Output filename.
