Thanks, this looks good to me, there are just a couple of things to fix in tests.

Also, can you add a bullet point in NEWS.md indicating the new feature and the PR number (and your github username if you want)?

[collioud]

Made a commit with the asked modifications.
Have a good night!

[etiennebacher]

Almost done, you just need to redocument. You can use task build-documents for that

[collioud]

Done.
Please note that I changed a bit the tests/testthat/test-csv-read.R file to be coherent with test-parquet.R.
When doing task build-documents, I also have modifications in some doc files (like man/Series_to_r.Rd, man/Series_class.Rd, etc.), but it looks like it is unrelated to this PR, as far as I know. I let the changes, but feel free to discard them...

[etiennebacher]

I cleaned up the PR, I think the extra changes in .Rd files were due to the fact you don't have the latest version of roxygen2.

That's a nice first contribution, thanks @collioud!

You made this easy!
Thanks again for such a nice and useful project!
