wrap substrate BIP39 for ed25519

[noot]

Task summary

• substrate uses a non-standard BIP39 implementation
• see https://github.com/paritytech/substrate-bip39
• this is currently implemented in go-schnorrkel for sr25519 https://github.com/ChainSafe/go-schnorrkel/blob/master/bip39.go
• however needs to be implemented for ed25519 keys as well for usage with ext_crypto_ed25519_generate_version_1
• the schnorrkel library can be used, but will just need to port the resulting key to ed25519
