It's unclear when that stopped (or possibly whether it's ever worked), but "regular" commands which don't build in-place (e.g. a simple `setup.py build`) have not worked in a while, because the overrides on tasks trigger `build_regexes` before the task itself (to say nothing of invoking `build_regexes` directly). As a result, the build_dir does not exist yet unless there's an old build_dir remaining for some reason, and trying to create the file crashes. Ensure the build dir exists before trying to write `_regexes.py`. There's a minor TOCTOU in order to handle Python 2's `os.makedirs`, as it doesn't have `exist_ok`.

- removed version bound from `setup_requires`, allows building from source when only PyYaml 6.0 is available (and downloading 5.4 is not), ua-parser#121, ua-parser#125 - added type assertion to parser lookup, to make the error clearer on type error, ua-parser#122, ua-parser#123 - fixed `setup.py build_regexes` and `setup.py build` for non-in-place builds, ua-parser#127
