member not ordered in nccf_atm diag

the concatenation of the member is not ordered properly by nccf_atm_diag: ncecat tmp_mrso_19930501.fc7.nc tmp_mrso_19930501.fc0.nc tmp_mrso_19930501.fc1.nc tmp_mrso_19930501.fc5.nc tmp_mrso_19930501.fc3.nc tmp_mrso_19930501.fc4.nc tmp_mrso_19930501.fc6.nc tmp_mrso_19930501.fc9.nc tmp_mrso_19930501.fc8.nc tmp_mrso_19930501.fc2.nc tmp_cat.nc

this is sorted out replacing:

$(find . -maxdepth 1 -name "${varnew}*${MEM}*" | sed -e 's/\.\///g')

by

$(find . -maxdepth 1 -name "${varnew}*${MEM}*" | sed -e 's/\.\///g' | sort -u )

I am working on the solving it. People who might be affected @eexarchou @obellprat @mmenegoz @dvolpi @vguemas
