Incorporate older longline discard data as done in last assessment

[seananderson]

Should be relatively small. Based on a ratio of longline catches.

Last res doc:

The average annual ratio of discards to landings in the longline fisheries (2001-2006) was 22.7% for the inside stock and 3.2% for the outside stock (Table 3 and Table 5). These averages were applied to the longline landings from 1966-2000 to estimate that discards (tonnes) for the inside (Table 7) and the outside stocks (Table 8).

Then Table 8:

However, these values in 2001-2006 are (1) tiny and (2) now known to be much smaller than what was seen 2007 onwards. I'd rather exclude these and note the next version may want to try applying some other ratio going back further. These values are tiny and I've just finished re-running the model before I found table 8.

these are also weight but the fleet is now count - not worth the trouble for these small values
