New API methods

Features

• Last 24h traded volume queries are now possible with --volume-day option
• Latest price queries are now possible with --price option

• Updated Binance URL for withdrawal fees retrieval in public mode (without authentication). Private version is preferred though.

• Lower severity of logs in some cases
