Remove channels from level 0 files that are no longer available
These files were removed from the CSV data:
"doptotemp", # REMOVED 2020 SEASON
"doptosat", # % # REMOVED 2020 SEASON
"doptoppm", # l/kl (ppm) # REMOVED 2020 SEASON
"chlor", # REMOVED 2020 SEASON
"phyco", # REMOVED 2020 SEASON
I did what I could to make this work without rewriting all of the code. This was bad.
