Motivation ---------- smapp has a simple message signing functionality, which uses a wallet's keypair to sign text messages using Ed25519ctx. This functionality is used by, for example, Team24 to authenticate an sm1 address owner. The functionality is also supported by the third-party wallet implementation smeshwallet.com. Description ----------- This change adds a simple `smcli wallet sign` subcommand, which takes a wallet JSON and a message as arguments, signs the message, and outputs a smapp-compatible JSON structure of message, signature, and signer public key.
