refactor!: refactor the SDK to use the new crypto package

BREAKING CHANGE:
 - Bip32PublicKey removed from core and replaced by the Bip32PublicKeyHex type from the crypto package.
 - Bip32PrivateKey removed from core and replaced by the Bip32PrivateKeyHex type from the crypto package.
 - Ed25519PublicKey removed from core and replaced by the Ed25519PublicKeyHex type from the crypto package.
 - Ed25519PrivateKey removed from core and replaced by the Ed25519PrivateKeyHex type from the crypto package.
 - Ed25519KeyHash removed from core and replaced by the Ed25519KeyHashHex type from the the crypto package.
 - Ed25519Signature removed from core and replaced by the Ed25519SignatureHex type from the crypto package.
 - Hash32ByteBase16 removed from core and replaced by the Hash32ByteBase16 type from the crypto package.
 - Hash28ByteBase16 removed from core and replaced by the Hash28ByteBase16 type from the crypto package.
 - The KeyAgent interface now has a new field bip32Ed25519.
 - The KeyAgentBase class and all its derived classes (InMemoryKeyAgent, LedgerKeyAgent and TrezorKeyAgent)  must now be provided with a Bip32Ed25519 implementation on their constructors.
 - Bip32Path type was removed from the key-management package and replaced by the Bip32Path from the crypto package.
