This adds a new ZIGBEE_TAP link type to the wireshark connector block, prefixing an 802.15.4 TAP header to each captured frame.
It'll set the FCS to a 16-bit CRC to be compatible with the current ZIGBEE link type. Optionally, if a "channel" key exists in the pdu's dict, it will append the corresponding channel TLV.
