First NDLAr Configuration File

[alexbooth92]

Adding first NDLAr configuration file for running at NERSC. This configuration is an adaptation of 2x2_full_chain_flash_240819.cfg with a NERSC weights path and several tweaks made by Kazu to get it up and running for NDLAr. The diff of the 2x2 config and this new config is below. It has been tested in MicroProdN1.1. Note that the weights in the 2x2 config were already out of date in spine_prod at the time of doing the diff which is why the weight file name and not just the path changes.

Just a couple of minor changes but otherwise it looks good to me!
