subgrind v0.1.0

Initial release. 🎉

Fast vanity address generator for Substrate / Polkadot / Bittensor: grinds random BIP39 mnemonics (12 or 24 words) and derives SS58 addresses until one matches your regex. Supports sr25519, ed25519, and ecdsa, any SS58 network prefix, and multi-threaded grinding. Addresses match subkey / Polkadot.js exactly.
