Description

The purpose of this ticket is to request support for Pure EdDSA XML signature algorithm:
As defined in the https://www.rfc-editor.org/rfc/rfc9231.html 
http://www.w3.org/2021/04/xmldsig-more#eddsa-ed25519

Explanation
EdDSA is a modern digital signature algorithm that is designed to be faster and more secure than existing schemes. It is based on elliptic curve cryptography and is widely used in various applications, including secure messaging, cryptocurrencies, and more.
Support would enable to take advantage of the latest advancements in digital security and cryptography, and provide them with a more secure and efficient way to sign and verify data.
Because the algorithm is already supported by the dependency: santuario library, adding support for wss4j does not require much effort.
