Hard-Reset Command, Handling Reset-on-Connect Issues, API Changes

• Added: reset command to Hard-Reset the NodeMCU module using DTR/RTS reset circuit (like NodeMCU DEV Kit)
• Added: RAW output format to fsinfo command - feature requested on GitHub #13
• Added: --connection-delay option to fix broken reset circuits which cause a immediate hard-reset on opening the serial connection (dts/rts lines) #14
• Added: Documentation regarding to Reset-on-Connect Issues / Broken Reset Circuits
• Changed: Default baudrate to 115200 - newer firmware versions using automatic baudrate detection which allows to use higher connection speeds by default
• Changed: footprints of NodeMCU-Tool.js functions - port/baudrate are set globally by setOptions instead by each function
• Changed: logging-facility is used for global log output management
• Changed: Updated the serialport package to v4.0.0
• Changed: Function footprint of NodeMCU-Tool.fsinfo changed to function(port, baud, format) - format can be json, raw or null
• Bugfix: Silent mode was not completely silent - thanks to remcoder on GitHub #12
• Deprecated: NodeMcuConnector.onError callback will be removed in the future (replaced by logging-facility)
• Deprecated: ScriptableSerialTerminal.onError callback will be removed in the future (replaced by logging-facility)
