feat: implement DID registration with JWT signing

- Add full DID registration flow matching TypeScript version
- Implement ES256K JWT signing with PEM key format
- Add async/await support for JWT operations
- Improve error handling and debug output
- Add rich documentation and type hints

Technical Changes:
- Convert private key to PEM format for JWT signing
- Match TypeScript's JWT payload structure
- Add proper JWT header with ES256K algorithm
- Implement async functions for JWT creation
- Add detailed debug output for JWT parts

Documentation:
- Add module-level docstring with flow description
- Add function-level docstrings with examples
- Document security considerations
- Add technical details and error handling info

Dependencies:
- Add cryptography for key format conversion
- Add jwcrypto for JWT operations
- Update requirements.txt with versions and comments

This commit implements the complete DID registration flow,
matching the TypeScript implementation's behavior and
adding comprehensive documentation and error handling.

+DID Creation and Registration Flow
+@author Matthew Raymer
+
+This module implements the creation and registration of Decentralized Identifiers (DIDs)
+with the endorser.ch service. It handles the complete workflow from mnemonic generation
+to DID registration.
+
+Flow:
+1. Generate or load mnemonic seed phrase
+2. Derive Ethereum keys and address
+3. Create DID identifier
+4. Initialize account
+5. Create signed JWT
+6. Register DID with endorser service
+
+Features:
+- Secure mnemonic generation and storage
+- HD wallet key derivation
+- ES256K-R JWT signing
+- DID registration with endorser.ch
+- Persistent mnemonic storage
+
+Dependencies:
+- mnemonic: For seed phrase generation
+- eth_account: For Ethereum account operations
+- eth_keys: For key manipulation
+- web3: For Ethereum utilities
+- requests: For API communication
+
+Usage:
+    python new_flow.py
+
+Environment:
+    API_SERVER: Endorser API endpoint (defaults to test server)
