[FLO-2D] Max datasets not shows

[PeterPetrik]

for some files, FLOW DEPTH and MAX datasets are not shown

data: _Projects/FLO-2D/bugs/mdal_382

looks like HDF5 file IS present AND does not contain the depth/MAX datasets: (it is the same for https://github.com/lutraconsulting/MDAL/tree/master/tests/data/flo2d/BarnHDF5 too). If TIMDEP.HDF5 is present, TIMDEP.OUT, DEPTH.OUT and VELFP.OUT reading is SKIPPED.

ncdump -h TIMDEP.HDF5
outputs:

	phony_dim_9 = 1 ;

note that this behaviour is same for few released already (e.g. QGIS 3.14):
