Exclude helicopters from likely fishing and fix dates

[bitsofbits]

Changes

• Exclude helicopters from likely-fishing query.
• Extend date range for 2016 through August (2016-08-31). This adds:
  • ~46,000 active vessels
  • ~8,000 likely / known-and-likely vessels
• Remove extra January 1st from queries. (yyyy-01-01, YYYY-01-01) ➡️ (yyyy-01-01, yyyy-12-31). (Table_date_range is includes the date endpoints, it's not half open like most Python comparison constructs: https://cloud.google.com/bigquery/query-reference#table-date-range). This removes:
  • ~200 active vessels each year
  • ~60 likely / known-and-likely vessels each year.
