An array of size 5*data.length/4 which contains the Z85-encoded text, excluding the terminating zero byte. This will be a slice of dest if it is provided.
$(COREF exception,RangeError) if dest is given but is too small.
ZmqException if $(ZMQ) reports an error (i.e., if data.length
is not a multiple of 4).
$(ZMQREF zmq_z85_encode())
Encodes a binary key as Z85 printable text.
dest must be an array whose length is at least 5*data.length/4 + 1, which will be used to store the return value plus a terminating zero byte. If dest is omitted, a new array will be created.
