Added ability to specify "aid" for Accessories 

If not specified, "aid" defaults to an index number representing the order in which the Accessories were created.   Values are stored as uint32_t  (which is more limited than HAP requirements of uint64_t, but makes the code easier).

TO DO:  Must add validation to ensure duplicate aid values are not used.
