postcard-cobs 0.2.0

This is an implementation of the Consistent Overhead Byte Stuffing (COBS) algorithm. COBS is an algorithm for transforming a message into an encoding where a specific value (the "sentinel" value) is not used. This value can then be used to mark frame boundaries in a serial communication channel.
