Implementation of the IEEE 802.15.4 dissector ignores the Auxiliary Security
Header of the MHR (see IEEE 802.15.4-2006 specs p.138).
The attached patch, add two things :
1) Support for dissecting the Auxiliary Security Header
2) Add a preference option to force the dissection of
the FCS field as being in the TI CC24xx format
