rewrote slugify func with radon

[IvanChumakov]

Made some changes in slugify function using the Radon utility (reduce the cyclomatic complexity of the function)

This is probably worth doing, but it could do with some tidy-up.

In particular:

• the docstring has vanished
• _ensure_unicode is redundant since python3
• _truncate_text takes default_separator instead of referring to the global DEFAULT_SEPARATOR
• _adjust_separator takes both default_separator and separator
• _apply_replacements, _adjust_case, _process_stopwords and _adjust_separator all do an early return if not enabled on entry. This would be clearer outside the functions, and shows that _adjust_case really just obscures a call to .lower().

I also think _safe_sub should be wrapping repl, not re.sub, but this would be a change in behaviour.

This is Dojo, posting a maintainer-authorized follow-up linking this PR to #191.

The wholesale complexity-driven rewrite is not adopted. Focused helper changes in #191 should not be read as integration of this historical patch.

The default algorithm remains legacy; improved output rules are opt-in. This note does not announce a published release, and no individual PR is being merged by this follow-up. Thank you for the contribution and discussion.
