add file_size_bytes to to_parquet

[nicornk]

Wasn't able to run the tests locally, as pytest fails for me with an error related to cmake not found, even though it's present.

implementation copies the row_group_size_bytes approach.

this kwarg would also be very useful!

@evertlammerts would you be able to pull this in?

@nicornk it'd be good if you can run tests either locally or in your personal GH first (preferably both :)). I see that the tests didn't run in your CI because your fork doesn't have the tags. If you've set the correct upstream then you should be able to get them with git fetch --all. See more on how to set up your dev env here: https://duckdb.org/docs/stable/dev/building/python Running tests for duckdb prs is good practice in general because we're low on CI runners most of the time, but around releases (such as now) it's especially important to use CI only when you've a good idea that tests are passing.
