compile.R removes erroneous "-9999" for WTCPUE, should be for NUMCPUE

[zoekitchel]

For the three Alaska regions (EBS, AI, GOA), the compile.R code includes mutate(wtcpue = ifelse(WTCPUE == "-9999", NA, WTCPUE))). However, it is the NUMCPUE that has some seemingly erroneous -9999 values, not WTCPUE.

NB: there are also -9999 values for sst and sbt that could easily be removed.
