SAGA grib crashes QGIS

[saberraz]

Not sure where this tickets belong to: here, Crayfish or QGIS!!

But grib file generated by Crayfish for SAGA flow direction crashes QGIS. Here is the output of mdalinfo:

mdalinfo 0.5.90

I get this in QGIS 3.10:

Here is a sample output from Crayfish converted SAGA flow direction to GRIB: flowDir.grb.zip

It seems that I ran out of memory just before the crash. The QGIS memory usage was 14 GB for loading the above file (less than 300 mb)!!

@saberraz is this still an issue with 3.16?
