Benjamin Valentin d18a304267 sys/coding: add XOR based coding module ... This implements the XOR based error-correction code described by Jürgen Fitschen (@jue89) at the RIOT Summit. A parity byte is generated for each 3 payload bytes, then the payload array is transposed by interpreting it as a 2D matrix with height of 3. This is to reduce the chance of consecutive bytes ending up in the same packet. This allows to recover one in 3 lost data packets (if parity packets are received).
