// Based on code by Jacques Fortier.
// "Redistribution and use in source and binary forms are permitted, with or without modification."
//
// Consistent Overhead Byte Stuffing is an encoding that removes all 0 bytes from arbitrary binary data.
// The encoded data consists only of bytes with values from 0x01 to 0xFF. This is useful for preparing data for
// transmission over a serial link (RS-232 or RS-485 for example), as the 0 byte can be used to unambiguously indicate
// packet boundaries. COBS also has the advantage of adding very little overhead (at least 1 byte, plus up to an
// additional byte per 254 bytes of data). For messages smaller than 254 bytes, the overhead is constant.
//
// This implementation is designed to be both efficient and robust.
// The decoder is designed to detect malformed input data and report an error upon detection.
