Hotfix to Fix LDAS PR #568

[mathomp4]

Description

In testing MAPL 2.23.0 with the LDAS it was found that it ran into issues with binary History output. History kept saying that the binary output file existed before writing. @bena-nasa could only really see this in the GCM when more than one file was written at the same time step, but the LDAS could do it with one.

So, for now we only do the "file exists" check with netCDF4 output. A reading of GETFILE makes me think it should do something similar for binary...but not sure.

Motivation and Context

Let's the LDAS use MAPL 2.23

How Has This Been Tested?

This has been tested by @biljanaorescanin with the LDAS and it fixes their issue. We will test with the GEOSgcm before merging.

I'm going to block this until it can be tested with GEOSgcm. Should be a trivially zero-diff fix for the GCM (we don't do binary History) but better safe than sorry.

Sigh. Stupid GitHub Actions. I might as well fix it in main too.
