Documentation error for clearance argument in \imagecell

[mayjs]

Hello, thanks for creating this package!

While creating my custom page layouts I noticed that the documentation for the clearance argument in the \imagecell macro seems to be wrong about the order of arguments when specifying values for all sides. The documentation states that the order should be clearance=<left> <bottom> <top> <right>, but it appears to be clearance=<left> <bottom> <right> <top>.
