Support truncate_ragged_lines option for reading CSV files

[jvdp]

Hi,

Thanks for the library! I'm getting good use out of it.

Polars can give an error message like:

found more fields than defined in 'Schema' (RuntimeError)

Consider setting 'truncate_ragged_lines=true'.

This PR adds support for it in the bindings.

Hi @jvdp, thanks for the PR. Happy to include, but please keep the arguments and code in the same order as py-polars for maintainability.

Thanks for updating. However, a lot of the code is still out-of-order (Rust code, Ruby code, @param docs).

Fixed now! Some notes:

• py-polars doesn't seem to have this arg on the batched method: https://docs.pola.rs/py-polars/html/reference/api/polars.read_csv_batched.html
• there's some pre-existing inconsistency in call order: https://github.com/ankane/polars-ruby/blob/master/ext/polars/src/lazyframe/mod.rs#L118

Looks great, thanks! Will sync the existing code in a follow-up commit.
