Develop index for Pacific Halibut as a special case (since all hooks are enumerated) #15

Check the data. Download of 2020 data for non-halibut species didn't seem to include halibut, but earlier code seemed to work for previous years. Needed for gfsynopsis and herring predators work.

Commits to 9ac16fb include the 2020 data (by updating countData2020 in data-raw/iphc-2020-data.rmd). Sticking with the usual analyses for Pacific Halibut, even though could generate an index using all the hooks. But Series A scaled and Series B scaled look pretty similar, so would give similar results anyway. If doing detailed halibut work someone would use the raw data anyway (though I couldn't see 1997 on IPHC website).
