🚀 API: adding SHA256 to the exclusion list and a new element in the subscribers method

We have introduced further changes to our API:

• Adding SHA256 encrypted email addresses to the exclusion list: 📧 This is done using the POST method, and the request simply needs to include the API key and the ID of the exclusion list to which the address will be added.
• New element in the subscribers method: 🔄 In the Subscribers method, we have expanded the StateOnLists element to include UnsubscriptionDate information. This allows users to know the exact date their customer unsubscribed from any subscriber list. The unsubscription date is returned only when the customer’s status on the list is Unsubscribed.
