Midea climate support (#1328)

* Added support for Midea IoT climate devices via UART interface (USB-dongle) * Fixed lint checks * Fixed lint checks * CODEOWNERS update * Clang-format * Clang-format * Add network device notification message support (show WiFi sign on devices) * Make wifi_signal_sensor optional component * Some optimization * Optimizations and code formatting * Fixed lint checks * Fixed lint checks * Fixed sign error * Code changes * Network notify repeat every 10 min * Added log messages * Fixed lint checks * Refactoring: MideaClimate => MideaAC * Using enums instead literals in Midea states * Enum changed to be more correct * Shrink notify frame to 32 bytes * Fixed lint checks * Change notify frame appliance type to common broadcast * Control optimization * Fixed control error * Control command now don't reset others uncontrollable properties of device * Fixed lint checks * Some optimization * on_receive callback give const Frame * Fix control * Fixes * Some minor changes * Fixed lint error * No dependency from wifi_signal sensor for stretched WiFi icon. New option: stretched_icon instead wifi_signal_id. * Fix option name * Added export of outdoor temperature as sensor value * Fixed lint errors * Fixed pylint error * Minor fix * Fix temperature overflow in some cases * Added answer on QueryNetwork command from appliance. Now don't wait for ack on 0x0D command. * Fix lint error * Added humidity setpoint optional sensor * Added boolean options 'swing_horizontal' and 'swing_both' * Added debug frame output * Added debug frame output * Fix lints error * Some debug output optimization * Fix lint check * Some code optimization: adding templates * Fix lint error * Added sensors device classes * Python code reformatted with black formatter * RX frame debug message RX frame debug message now prints before checking * Remove CRC check for receiving frames * Added experimental power usage option * Added power usage option * Fixed lint errors * Major changes. See esp-docs. * Added tests in test4.yaml * Added tests in test1.yaml * Added wifi dependency * Fix test1.yaml * Some fix :) * One more refactoring * One more refactoring * One more refactoring
