Legibility change: We now log Data as two-byte spaced at Ble Transport Level

So, instead of reading incoming and outgoing bytes as 0x03000177 we show them as 0300 0177. I think this is easier to read and compare bytes when checking whether something is working as expected or not. It also matches how Apple's Packet Logger (Sniffer) Developer tool shows bytes.
