## Issue Addressed Fixes #2141 Remove [tempdir](https://docs.rs/tempdir/0.3.7/tempdir/) in favor of [tempfile](https://docs.rs/tempfile/3.1.0/tempfile/). ## Proposed Changes `tempfile` has a slightly different api that makes creating temp folders with a name prefix a chore (`tempdir::TempDir::new("toto")` => `tempfile::Builder::new().prefix("toto").tempdir()`). So I removed temp folder name prefix where I deemed it not useful. Otherwise, the functionality is the same.
