What configuration options does the slugify function accept?

The slugify function accepts the following configuration options (all optional):

1. separator — Type: string, Default: '-' Defines the character used to separate words in the slug.

2. lowercase — Type: boolean, Default: true Controls whether the slug is converted to lowercase.

3. decamelize — Type: boolean, Default: true Converts camelCase to separate words (e.g., fooBar → foo bar).

4. customReplacements — Type: Array<string[]>, Default: [['&', ' and '], ['🦄', ' unicorn '], ['♥', ' love ']] Allows you to define custom character replacements that run before other transformations.

5. preserveLeadingUnderscore — Type: boolean, Default: false Preserves a leading underscore if the input string starts with one.

6. preserveTrailingDash — Type: boolean, Default: false Preserves a trailing dash if the input string ends with one.

7. preserveCharacters — Type: string[], Default: [] Allows you to preserve specific characters in the slug (cannot contain the separator). Useful for URLs that need to preserve characters like #.

8. transliterate — Type: boolean, Default: true Controls whether to transliterate characters (convert accented characters and non-Latin scripts to their Latin equivalents).

9. locale — Type: string, Default: undefined The locale to use for language-specific transliteration. See the @sindresorhus/transliterate package documentation for supported locales.

These defaults and behaviors are implemented in [index.js:L46-L111].
