shell script with applescript to activate scanner and set name of file

Canon TR7500 series printer/scanner shell script to execute the scan so I could use Termius (a terminal app for iPhone) on an iPhone to log in to my mac via ssh and type "scan" to start scanning.

Sorry not a lot of explanation on this version

   scan -setup

Is what I would do on my phone if I went to the printer and turned it on.
Often it's not set up correctly when the scan app comes on, so this should set it up at 300dpi and TIFF
It also uses python to drag the active scan window to the right so the paper can be aligned on the edge closest to the control panel which is only needed for A4 size.

   scan -c color
   scan -c bw

Set color or black & white mode.

   scan document-20200524-page-1

results in this file:

   scan document-20200524-page-1.tiff

or if that file already exists:

   scan document-20200524-page-1 1.tiff
