gdept/gdepw no longer outputted in domain_cfg.nc

[jenjar93]

The gdept and gdepw variables are no longer outputted by NEMO in the domain_cfg.nc.

Rather than removing these from all of PyBDY, would it be possible to introduce a script early on that calculates gdept/gdepw from the e3 variables?

@jenjar93 there is already a script in ./utils:
from .utils.e3_to_depth import e3_to_depth
see line 69 in nemo_bdy_zgrv2.py for example

For background, this looks related to a brief discussion in (#2 )
