Derive npub from nsec given as parameter
``` python
import argparse
import asyncio
from nostr_sdk import Keys, init_logger, LogLevel
async def main(nsec):
init_logger(LogLevel.INFO)
keys = Keys.parse(nsec)
public_key = keys.public_key()
print(f"Public key (hex): {public_key.to_hex()}")
print(f"Public key (npub): {public_key.to_bech32()}")
if __name__ == '__main__':
parser = argparse.ArgumentParser(description='Fetch all relay from a given nsec')
parser.add_argument('nsec', type=str, help='The nsec of the user')
args = parser.parse_args()
asyncio.run(main(args.nsec))
