Additional Cargo bay parameter

Door hinge location:

1. For now sideway hinges location only available at 0 and 180 degrees, splitting the bay exactly in half
   The additional options allows the hinge to move up or down
   ~ Example: 60 and 120 degree in a weapon bay style
   ~ Example: 90 on 1 side (no hinge), 170 on the other side in a suitcase / trunk (car) style

2. For clamp shell style, hinge location becomes seam location
   ~ Example: 270 degree on both sides - cargo bay turns into movable nose cone like the one on Komodo capsule
   ~ allow multiple cargo bay section to use the hinge on the root part, so the player could make a nose cone with diameter transition and it would not split into multiple parts when opened, even free from the trouble of using rotators and inlet / paneling to build such a nose cone.

3. For sliding door style: when the door opens, the moving part could be hidden inside the base - like using an invisible box to hide it (even in none circular cargo bay) so there's no part sticking out from the base
