feat: handle better arXiv's "citation key" imported from DOI

- Add a new dependency `rand` version `0.8` to the project
- Modify the `format_bibtex_entry` function for better readability and citation key cleaning
- Introduce logic to clean the citation key by retaining only alphanumerical characters and underscores
- Limit the citation key to the last 14 characters if it exceeds that length
- Add a new `file` field to the BibTeX entry using the provided file path
