Describe the bug
In the generated dataclass code a "normal" false appears instead of the python version.

To Reproduce
Steps to reproduce the behavior:

1. Create a CREATE TABLE statement, containing this column: edited boolean DEFAULT false,
2. Generate the dataclass: create_models(ddl, models_type="dataclass")
3. The dataclass has this line: edited: Optional[bool] = false

Expected behavior
false -> False

Screenshots

CREATE TABLE Material
    (
        id integer,
        name      string,
        edited   boolean DEFAULT false,
        deleted  boolean DEFAULT true,
        PRIMARY KEY (id, name)
    );

@dataclass
class Material:

    id: int
    name: str
    edited: bool = false
    deleted: bool = true

If you like a can present a possible fix. In the from_ddl.py and prepare_data function I would change the bool.
