L: Add graphics pipeline on Jet to plot EMC parallel -- RRFS_A.

[christinaholtNOAA]

EMC is running real-time RRFS prototype 1 based on the RRFS_dev1.

We should try to add these real-time runs to our verification and plotting process.
Ming is transferring the results to JET:

/mnt/lfs4/BMC/rtwbl/mhu/wcoss/emc/rrfs

The directory looks like:
rrfsp1.YYYYMMDD/HH
