There might be, but most of the functionality of "dissect_per_boolean()" 
isn't used if the hf_index value is -1, which it is in your code.
Perhaps the loop should do the bit-extraction itself, rather than having 
dissect_per_boolean() do it (and it can probably even check the 
bit-alignment of the offset and only fetch each byte from the tvbuff once).
That would probably perform well enough.
