Deprecate the use of `NA` as model for direct injection node
The use of NA
as model in the GRiwrm object has many pitfalls:
- it's not homogeneous with other models since new reservoir and diversion nodes
- it's a hell to make clean conditions on the model with
NAs
and it's a source of bugs.
I propose to :
- deprecate
NA
and invite to use "DirectInjection" - Convert
NA
to "DirectInjection" inCreateGRiwrm
with a warning - adapt all the code to this new way of doing
