Super simple command-line parser for Arduino

Super simple commandline processor for Arduino environments. Features:

• super small and simple codebase, easy to modify
• provide minimal input editing (backspace)
• register commands, let commands parse args

How it works

• register command word callbacks using addCommand()
• in the callback, use getArg() or getRest() to get next arg or rest of commandline for parsing
• register default callback using setDefault() to print help/error message
• for interactive input processing, use CommandParser(HardwareSerial *serial) constructor and call loop() in sketch's own loop()
• for batch processing (for example, command recieved via MQTT or HTTP) use CommandParser() constructor and parseLine()
