Update join_tracking_table_crossings_vw.sql (#599)

* Add WCRP columns to wcrp_watersheds.csv

Column shows which wcrp the watershed belongs to

* Added migration files

db.v0.5.3 includes join_tracking_table_crossings_vw.sql and migrate.sh

* Add wcrp column to wcrp_watersheds

Added column in table creation

* Moved wcrp column creation

- Added statement to add the wcrp column to bcfishpass.wcrp_watersheds
- removed the change from db/v0.5.0/sql/tables/wcrp.sql

* run add column wcrp to wcrp_watersheds on all systems

* Update join_tracking_table_crossings_vw.sql

- Added right join so excluded structures with no feature in crossings_wcrp_vw show up in the joined table.

* Update join_tracking_table_crossings_vw.sql

- Modified join to include crossings in bcfishpass.crossings_wcrp_vw that are not in the tracking table but are in the WCRP and where all_spawningrearing_km > 0.

* Update join_tracking_table_crossings_vw.sql

Altered condition to ensure all features from the tracking table are in the joined output view.
