commit c8c3d29af93967e7b28681f76ccac4604680b21f

    Book: corrections in the extended PSF tutorial
    
    Until now, the following typos were present in the extended PSF tutorial:
    
     - 'cat.fits' file was extra and it should have been removed (it was just a
       demo, not meant to be used later in the tutorial).
    
     - An 'rm' was forgotten and in stamp steps the name of input
    
     - The new name for Segment's output was not used when building the outer
       stamps.
    
    With this commit, a command for removing the 'cat.fits' is added and the
    'rm' has been added in the first of the command and finally the name of the
    input and segment of the stamps step are corrected.

 We only have two stars, but they if you zoom into their centers, you will see 
that they don't have any major bleeding-vertical saturations any more!
