+One-line Summary: Update fates tag with missing land use data check fix
+
+Purpose and description of changes
+----------------------------------
+
+This update brings in fates-side changes which allow for checking of
+fates land use data that uses either NaN or non-nan fill values.  This
+also updates the fates land use data tool tag which captures the
+associated netcdf write encoding changes to ensure that the land use
+data will use non-nan values consistent with the latest default datasets.
+
+
+Bugs fixed
+----------
+List of CTSM issues fixed (include CTSM Issue # and description) [one per line]:
+Resolves #3789
+
+Notes of particular relevance for developers:
+---------------------------------------------
+NOTE: Be sure to review the steps in README.CHECKLIST.master_tags as well as the coding style in the Developers Guide

+Changes to tests or testing:
+- Removes the FatesColdLUH testmods from the expected failures list
