Ability to provide entropy when generating a keypair

[steida]

BIP85 describes a way how entropy can be derived deterministically from a BIP32 root key, for example, a BIP39 mnemonic (24 words) commonly used in cryptocurrency wallets.

The ability to derive a keypair directly from the mnemonic would improve Themis DX I suppose.

@steida no ETA rn, as it's not one of the features users ask for. it's moved to a backlog to consider.
