Bugs in edgy rect placement in updateBinSize()

[JohannesHoffmann]

This solves the bugs in #55

What have i done:

• added fit or not fit check in extra test on rotated node to check for its better choice
• removes padding on fit comparisons

I have doubts with the padding issue and my solution. It rotates only the fourth why not all? Is my solution correct?

I have a questin right here. I struggled a lot to reproduce the bugs because in maxrects-packer.ts the option for square is false and in maxrects-bin.ts the same option is true. Was hard to find this out. Should this be the same default options?

Due to doc's default value, square shall be default to false
