v0.4.0

Changes:

• Implemented detection of expires from the salt's URL-encoded parameters (provided as a Unix timestamp in seconds). The Expires HTTP header should now be used, however, it remains supported for backward compatibility purposes.

Example challenge with salt parameters:

{
  "challenge": "...",
  "salt": "xxxxxx?expires=1715523102"
}

The latest version of the altcha-lib package (v0.3) now fully accommodates the new salt parameters and expiration functionality. For detailed information, please refer to the documentation.
