Snowflake File Format not supported.

[br-lewis]

The Snowflake dialect doesn't support DDL commands for File Format.

Running

Parser::parse_sql(&SnowflakeDialect {}, "CREATE FILE FORMAT my_file_format").unwrap();

Results in

thread 'main' panicked at src/main.rs:7:48:
called `Result::unwrap()` on an `Err` value: ParserError("Expected: an object type after CREATE, found: FILE at Line: 1, Column: 8")

I could try adding it myself but I wanted to check first since there's already a FileFormat in the ast module. It looks to be meant for something else in the other dialects so should I expand that or implement a snowflake specific one?
