Netcdf gridded output to file with fixed name

[ajhenrique]

NCEP operations require that ounf output to a fixed-name file. Currently a quick-fix is used in ww3_ounf.ftn:

! For NCEP application, requires fixed netcdf file name
FNAMENC='ww3.gridded.nc'

This issue is a request for a feature to allow users choosing that in ounf.inp.

@mickaelaccensi said: "I've already had this request a few months ago, an easy feature to implement would be to set the number of characters in date [4(yearly),6(monthly),8(daily),10(hourly)] to 0 to not have any time specification in the filename.
That's easy to implement so I can do it on a feature branch"

@ajhenrique Do you want me to implement it on this branch or is better if I create a new feature branch to implement it ?

As we discussed, please implement on a feature branch. Thanks!

@ajhenrique, is it ok for you if setting ndates=0 in ww3_ounf.inp or ww3_ounf.nml to define the output filename as a fixed name by replacing the date by 'field', for example ww3.field.nc or ww3.field_hs.nc ?
