Hello,

I've built the tool to generate vanity Tor Onion Service addresses:

    $ onion-vanity-address allium
    Found allium... in 12s after 558986486 attempts (48529996 attempts/s)
    ---
    hostname: alliumdye3it7ko4cuftoni4rlrupuobvio24ypz55qpzjzpvuetzhyd.onion
    hs_ed25519_public_key: PT0gZWQyNTUxOXYxLXB1YmxpYzogdHlwZTAgPT0AAAAC1ooweCbRP6ncFQs3NRyK40fRwaodrmH572D8py+tCQ==
    hs_ed25519_secret_key: PT0gZWQyNTUxOXYxLXNlY3JldDogdHlwZTAgPT0AAAAQEW4Rhot7oroPaETlAEG3GPAntvJ1agF2c7A2AXmBW3WqAH0oUZ1hySvvZl3hc9dSAIc49h1UuCPZacOWp4vQ

The tool checks ~45'000'000 keys per second on a laptop which is ~2x faster than widely-used mkp224o https://github.com/cathugger/mkp224o

I've explained key performance difference here https://github.com/AlexanderYastrebov/onion-vanity-address?t...

Would love your feedback, thanks!
