2 Second section of namcouple for `OUTPUT` fields

The first 3 lines for fields with status OUTPUT are as follows:

 CONSFTOT  CONSFTOT 1  86400   1  flda3.nc  OUTPUT
 128  64  128  64 atmo   atmo 
 LOCTRANS

where the different entries are:

Field first line:
- the source symbolic name must be repeated twice on the field first line
- 1 : UNUSED but still required for parsing
- 86400 : output period for the field, in seconds
- 1 : number of transformations to be performed by OASIS3-MCT on this field
- flda3.nc : name of the coupling restart file for the field (32 characters maximum); needed only if a LOCTRANS transformation is present
- OUTPUT : field status
Field second line:
- 128 : number of points for the source grid first dimension (optional)
- 64 : number of points for the source grid second dimension (optional)⁹
- 128 : number of points for the target grid first dimension (optional)
- 64 : number of points for the target grid second dimension (optional) $^{1}$
- atmo : prefix of the source grid name in grid data files repeated twice (80 characters maximum)
The third line is LOCTRANS if this transformation is chosen for the field. Note that LOCTRANS is the only transformation supported for OUTPUT fields.
