Retrieves current wallet balance: total and unlocked.
Outputs:
- balance — unsigned integer; total fund, that the wallet has (unlocked and locked coins).
- unlocked_balance — unsigned integer; unlocked funds, i.e. coins that are stored deep enough in the blockchain to be considered relatively safe to spend. Only this many coins are immediately spendable. Unlocked_balance is always less or equal to balance.
