Support "quoting" column names

When passing a "quoting" column name to `binary_copy_to_table`, psqlpy raises syntax error. Callers have to wrap those columns in a double quote by themselves. It would be great to support this in the library.

workaround,
```python
async def main():
    res = await conn.binary_copy_to_table(
        columns=[
            '"a-b"',
        ],
        ...
    )
```
