Added STRAIGHT_JOIN token to the parser

The sql parser not split the STRAIGHT_JOIN token into a new line.

Before:

```sql
SELECT *
FROM table_A AS TBA STRAIGHT_JOIN table_B AS TBB ON (TBA.id = TBB.id) STRAIGHT_JOIN table_C AS TBC ON (TBB.id = TBC.id) 
```

After:

```sql
SELECT *
FROM table_A AS TBA
STRAIGHT_JOIN table_B AS TBB ON (TBA.id = TBB.id)
STRAIGHT_JOIN table_C AS TBC ON (TBB.id = TBC.id) 
```
