Udpsocket (#507)

* udp socket refactor from reuss: closing socket before throwing for bind error in constructor, closing socket at destructor and not at shutdown to allow other thread to read with a -1, so the object can still be accessed

* check for size of packet for every detector

* nullptr to unique ptr to call its destructor, when deallocating resources moved out of shutdown

* minor
