CLI input for autopipeline spacing variable not clear

[strixy16]

The provided description for the --spacing flag in the CLI call of autopipeline is not clear.

It currently has:
--spacing [Tuple: (int,int,int)]

which to me indicates that it should be written as:
--spacing (0,0,0)

but that returns the error:
imgtools Automatic Processing Pipeline.: error: argument --spacing: expected 3 arguments

The actual correct input to get it to work is:
--spacing 0 0 0

This might be intuitive to those familiar with bash CLI and scripting, but it wasn't to me. Can we give a proper example of how to input all of the arguments?
