Yoy may divide the hex string into shorter parts that fit within un
unsigned long and  read them into unsigned long using std::istream,
then convert them into std::bitset or boost::dynamic_bitset, and
further convert them into binary representation using std::ostream.

As you seee, you may do it only with standara library components, but
ther is no direct way to do it, you must go through unsigned longs
always.
