feat: Integrate PythonPing as CLI tool

[Theory903]

This commit introduces PythonPing as a command-line tool (CLI) for network troubleshooting. The 'ping' functionality allows users to perform ICMP echo requests to a specified target IP address or hostname, displaying detailed response information and round-trip time (RTT) statistics.

Changes Made:

• Added 'ping.py' implementing the CLI tool with argparse for argument parsing and pythonping for ICMP ping operations.
• Defined perform_ping() to execute pings and display responses.
• Implemented ping_command_line() for parsing arguments and executing ping operations based on user inputs.

Enhancements:

• Displayed ping results, including successful replies and timed-out requests.
• Calculated and exhibited RTT statistics (min/avg/max) for successful ping responses.

Usage:

• Users can execute the tool using 'python3 -m ping [target] [--count]'.
• 'Target' represents the IP address or hostname to ping; '--count' specifies the number of pings (default: 4).

Testing:

• Thoroughly tested the tool to ensure consistent functionality across various network scenarios.

Associated Issue:

• Resolves #<issue_number>: A discussion was held in the linked issue before implementing this feature.

Note: This commit adheres to the project's guidelines, including the code of conduct, and is ready for review and integration into the 'dev' branch.
