Add OMEMO Support for Individual Messaging

[vsevex]

The goal is to make the client OMEMO-compatible for private messaging. OMEMO is an end-to-end encryption protocol that offers safe XMPP client-to-client communication. Users will be able to have private and secure encrypted discussions by utilizing OMEMO for individual messaging.

Tasks:

• Integrate OMEMO key management functionality.
• Implement OMEMO session management logic.
• Enable message encryption using OMEMO for outgoing individual messages.
• Enable message decryption for incoming individual messages using OMEMO.
• Test and validate OMEMO functionality using XMPP clients that are compatible.
• Update documentation to include information about OMEMO support for individual messaging.
