UNM_process_10hz_main can't process LiCor 7200 TOB1 files.

[gremau]

We now have LiCor 7200s at two sites. These instruments have different data outputs than the 7500 IRGAs which means the 10hz processing pipeline needs to be revamped to read and process these files.

1. Variables read into dataset in read_TOB1_file.m are different in new TOB1 files.
2. TOB1 files have a different filename (irga2). Currently these are ignored by get_ts_filenames.m
3. There are probably other aspects of processing that will need to change.
