Allow 180 rotation of rectangular crafting machines after placement

[TwentyEighty]

If you have an entity based on the assembler prototype with a non square collision box and a fluid box, it's not possible to rotate the entity after placement. For entities like boilers and generators, this is possible and it rotates them 180 degrees. The assembler behavior is unexpected and seems arbitrary.

I suggest to allow the assemblers to have similar behavior to boilers for this case.
