Comments are not handled correctly 

Hello David 👋 

I just noticed that comments are not handled correctly when formatting the SQL queries. 
For example
```sql
SELECT * FROM table_a
WHERE user_name="john doe"
/* just a comment */
ORDER BY user_id
```
is transformed into 
```sql
SELECT *
FROM table_a
WHERE user_name="john doe" / *
```

PS: Thanks for the tool!
