Switch to secondary weapon Added button to switch to the previously used secondary weapon

When engaging in frequent aerial combat or flying aircraft on land, as the variety of weapon loadouts increases, accidentally pressing the secondary weapon button too quickly sometimes requires pressing it again. In the split-second critical situations of flying vehicles, this often leads to missed opportunities. I hope to add an option to return to the previous secondary weapon. This would allow players who accidentally select the wrong secondary weapon to press a button to quickly return to the previous one and select the desired loadout.
