v0.0.2-beta

Overview:
This is the second beta release of the Denaro Wallet Client, developed by The Sycorax.

Changelog:

• Various updates to the README file.
• Updates to CLI help messages.
• Moved 'secure_cleanup' in 'wallet_client.py' to the 'DataManipulation' class of 'cryptographic_util.py'.
• Removed redundant 'secure_delete' function from 'wallet_client.py' because it was already in the 'DataManipulation' class.
• Most functions will now call the 'secure_cleanup' method in the 'DataManipulation' class whenever there is an error, return statement, or basically any exit point. This ensures that any (potential) sensitive variables are deleted but also purged from memory. This minimizes the potential risks associated with sensitive data lingering in memory. However performance is slower as a result.
• Fixed the path to the Denaro logo in the 'handle_new_encrypted_wallet' function. It was causing the script to error out when generating a new encrypted wallet with 2-Factor Authentication.
