## Which issue does this PR close? <!-- We generally require a GitHub issue to be filed for all bug fixes and enhancements and this helps us generate change logs for our releases. You can link an issue to this PR using the GitHub syntax. For example `Closes #123` indicates that this PR will close issue #123. --> - Closes #16260. ## Rationale for this change As mentioned in that issue, it's reasonable to autodetect a file suffix. For example, for gzipped CS it should be `.csv.gz`. ## What changes are included in this PR? Since the physical planner needs to understand whether compression was specified as a part of the abstract `FileFormat` trait, I extended it to provide a compression type. Based on this information, we're able to construct a new extension with a fallback to the original one (`.csv`). ## Are these changes tested? 1. Added unit tests 2. Run a manual example program `cargo run --example dataframe` and got a gzipped file `datafusion-examples/test_csv/kuz6EXRCgJqdmob3_0.csv.gz` ## Are there any user-facing changes? If the user specifies a directory to write CSV files (not a single file path) and the compression type, then files will have `.csv.gz` extensions instead of `.csv`. <!-- If there are any breaking changes to public APIs, please add the `api change` label. --> -- This is an automated message from the Apache Git Service.
