Feature: Basic CLI

[sephynox]

High Level Overview of Change

This PR adds a basic command-line interface (CLI) for interacting with the XRP Ledger. The CLI provides essential functionality for common XRPL operations, making it easier for users to interact with the ledger without writing code.

Context of Change

The XRPL Rust library already provides a comprehensive API for programmatic interaction with the XRP Ledger. However, users often need to perform quick operations without writing a full program. This CLI addresses that need by providing a simple interface for common operations.

The CLI is implemented using the clap crate for argument parsing and leverages the existing XRPL Rust library functionality. It's designed to be extensible, making it easy to add more commands in the future.

Key Features

• Account Operations: View account information, transactions, and objects
• Wallet Management: Generate new wallets and derive wallets from seeds
• Network Information: Get current network fees and server information
• Transaction Handling: Sign and submit transactions to the network
• Address Validation: Validate classic and X-addresses

Implementation Details

• The CLI is conditionally compiled with the cli feature flag
• Commands are implemented in a modular way to allow for easy extension
• Error handling is robust, with user-friendly error messages
• Tests ensure that commands work correctly, with resilience to network issues
• The implementation supports both synchronous and asynchronous operations
