py-packageurl: updated to 0.10.4

0.10.4 (2022-10-17)
-------------------

- Refactor the purl2url functions and utilities

  - Split purl2url into `get_repo_url()` and `get_download_url()` returning
    accordingly a "Repository URL" and a "Download URL".
  - A new `get_inferred_urls` function is available to get return all
    inferred URLs (repository and download) values.
  - Add support in purl2url for npm, pypi, hackage, and nuget.
  - Package URL qualifiers can now be provided to `purl_from_pattern()`.
  - The `download_url` qualifier is returned in `get_download_url()` when available.

- Usage of `purl2url.purl2url` and `purl2url.get_url` is still available for
  backward compatibility but should be migrated to `purl2url.get_repo_url`.

- Include the `version_prefix` ("v" or "V") as a qualifier \ 
in build_github_purl
  This allow to infer valid URLs in the context of purl2url.
