- GHSA-6vqw-3v5j-54x4
- GHSA-jfhm-5ghh-2f97

This release upgrades the package dependencies to the latest versions and drops support for Python 3.7.

* New Delegation Proof Type {DID, GENERIC}
* New API Proof objects: APIProof, APIDidDelegationProof, APIGenericDelegationProof used in advanced api
(decouple api from crypto proof, deal with deleagtion proof type and content, backward compatible)
* New Advanced API helpers to create generic proof and allow delegation with generic proof
* New validation mode according to the proof type
* New Regisered document delegation proof type serialization

Make delegation_name parameter optional in high_level and regular APIs. If the parameter is omitted a random name will be chosen.
