matroskin 0.1.0

//! Implement `set.system.factory_reset` command
//!
//! Resets the device to its factory default settings.
//! This operation will revert network configuration, system passwords,
//! user permissions, API switch, web pool settings, saved pools,
//! power mode, and power limit. The device will reboot upon completion.
//!
//! - Command: [SetSystemFactoryReset]
//! - ApiDoc: <https://apidoc.whatsminer.com/#api-System-system_factory_reset>
