Added efficient floor limit

[Shmerlard]

I've added a simple limit to the efficent floor
the first image is the baisc floor, but sometimes its too thick
the second image is the regular efficent base which is too thin, and may cause problems with text cutout and the magnets holes are in the way

so i've added the parameter to limit it, -1 will disable the limit, and -2 will set it to be just above the magnet holes. as you can see in the 4th image

That's for the PR and detailed comment.

Not quite the same but floor thickness is another way to resolve the text issue. This will however also increase the material above the magnet.

yeah thats why i created the pr, id really like to hide the magents as much as possible
for bins bigger then 1x1 you still see the base
but for 1x1 its pretty much perfect for small items like nuts and washers where every space is needed
