[vscript] DP12/DBS double shooting mechanism for pumpshotugn

Now the DP-12 (Pump Shotgun) can fire two shells in rapid succession!

This mod adds a new firing mechanism to the Pump Shotgun, inspired by the real-life DP-12 double-barrel shotgun.

With each pump action, the Pump Shotgun can now fire two consecutive shots, just like a semi-automatic shotgun, without needing to pump between them!

After firing the second shot, you'll need to pump the shotgun again before firing the next pair.

Features

- Fire two shots in rapid succession with only one pump action. - No pumping required between the first and second shots. - Pumping is still required after every two shots. - Adjustable interval between the two shots (default: 0.25 seconds). - Modified reloading behavior to accommodate the DP-12 firing mechanism. - decrease 1 max magazine capacity when there still exists one shell in the barrel - Only affects the Pump Shotgun.
