feat: Change NAME depo output to nc instead of txt

Will has been sending both netcdf and txt versions of NAME results for a while now.
When fully adopted and txt results are no longer sent, this has the
advantage of smaller data load on storage and transfer.
Here, the nc has been implemented for deposition only, since it is a
straightforward change.
The environmental suitability input (NAME met output) still needs to
be done.
