* improve tools.lib.kbhit and tools.sim.lib.keyboard_ctrl * unpack more efficiently * minor improvements * agnos.py match spec better * manual_ctrl test missing queue arg * fix incorrect type annotation * queues are generic * varname reuse resulting in incorrect type inference * bytes().hex() rather than bytes.hex(bytes()) * a bit of type hinting stuff
