Hierarchical deterministic keys: Mnemonic backup phrases (BIP-39), Bip32 derivation on secp256k1 with xprv/xpub serialization, Slip10 for Ed25519, and DerivationPath for the m/44'/60'/0'/0/0 notation.

Types

`class Bip32`	A BIP-32 hierarchical deterministic key on secp256k1: Bitcoin, every EVM chain and most others derive their accounts this way from one `Mnemonic` seed.
`class DerivationPath`	A BIP-32 derivation path such as `m/44'/60'/0'/0/0`: a list of child indices, each hardened when written with `'`, `h` or `H`.
`class Mnemonic`	BIP-39 mnemonic sentences: the 12 to 24 English words a wallet shows as its backup, and the 64-byte seed `Bip32` and `Slip10` derive every key from.
`class Slip10`	SLIP-10 key derivation for Ed25519, the scheme Solana, Stellar, Cardano-style and Aptos/Sui wallets use on a `Mnemonic` seed.
