Adding ERF driver to NoahMP

[akashdhruv]

This pull request introduces driver for the ERF-model (https://github.com/erf-model/ERF). ERF is a C++ based application and we have developed a Fortran/C interoperability for NoahmpIO_type.

The interoperability layer corresponds to the latest functionality available in ERF after this PR is merged:

erf-model/ERF#2196

The Fortran part of the code is largely based on the HRLDAS driver and the C interoperability layer is available in the following files:

• drivers/erf/NoahmpIO.H
• drivers/erf/NoahmpIO.cpp
• drivers/erf/NoahmIO_fi.F90

We also provide CMake interface to build this driver. Once library is installed once can access NoahmpIO interface in C/C++ by simply including the header file #include <NoahmpIO.H>. See this example here:

We also introduced another header file:

• drivers/erf/NoahArray.H

which casts C pointer to a Fortran style array to maintain consistency between access of array in Fortran an C++. See this example here:

https://github.com/AIEADA/ERF/blob/13adcaf76948fcd801bde456011de97065eb5dc6/Source/LandSurfaceModel/NOAH/ERF_NOAH.cpp#L203-L219

Please Squash and Merge this pull request if possible. We would prefer if the history is consolidated in a single commit with the title of the PR as the commit message.

Attached is a result from a successful run of a Chisholm View simulation performed using ERF on a linux workstation with AMD Ryzen 9 CPU. The simulation used 10 MPI processes with GCC compilers.
