Update iso c binding library

[hellkite500]

noah-owp-modular has extended its BMI implementation to a complete BMI imlementation:

NOAA-OWP/noah-owp-modular@88209a8
NOAA-OWP/noah-owp-modular@3a3e0a4
NOAA-OWP/noah-owp-modular@0ce6080

The ISO C Binding is currently implementing a custom BMI structure based on the original noah-owp-modular BMI implementation, and this needs to be updated to avoid ABI incompatibility:
The following blocks need to be uncommented and SOME implementation needs to be present here, even if it is a BMI_FAILURE indicating that this middleware doesn't support the functionality requested:

ngen/extern/iso_c_fortran_bmi/src/bmi.f90

Line 299 in 45d403e

! ! ! Get a reference to the given integer variable.

ngen/extern/iso_c_fortran_bmi/src/bmi.f90

Line 386 in 45d403e

! ! ! Set integer values at particular (one-dimensional) indices.

This issue can actually lead to seg faults and other odd behaviour when using current noah-owp-modular with ngen, since the ABI is different between ngen and the dynamically loaded module. This should be addressed ASAP.
