Check + then Change `galotago` to `galvul`

Galotago was invented by Mike J for 2004 paper. this is confusing many regional scientists.

1. Check whether any galotago records are present in recent NZFFD records (and check manual to see if this is a valid species code).

2. change code so that Galotago should have same IBI metrics as galvul.

"I also note that the “Galotago” group, useful for shoehorning multiple species into the Joy and Death 2004 groupings, is a bit of a misnomer as it is being used to represent multiple species distributed throughout southern New Zealand (i.e. beyond Otago, including Southland and Canterbury Regions, and Nelson City and Tasman Districts) as well as unidentified galaxias species which were previously recorded in the NZFFD as “galaxi” and could be your local whitebait run."

There are no gal.*tag in the fields taxonName, taxonCommonName, or taxonRemarks in the whole NZFFD database (ignoring case).

12 species codes are converted to galotago in our lookup table to get the 2004 code.

But there are no galotago in the species_ibi_metrics table.

Should we just change galotago to galvul, then, in the species code lookup?
Or create a galotago row in species_ibi_metrics with the same characteristics as galvul?
