--[[
A darktable plugin that tries to predict keywords based on the selected image.
This plugin uses photils-cli to handle this task. Photils-cli is an application
that passes the image through a neural network, classifies it, and extracts the
suggested tags. Everything happens offline without the need that your data are
sent over the internet.
ADDITIONAL SOFTWARE NEEDED FOR THIS SCRIPT
* photils-cli - https://github.com/scheckmedia/photils-cli at the moment only
available for Linux and MacOS
USAGE
* require this script from your main lua file
To do this add this line to the file .config/darktable/luarc:
require "contrib/photils"
* Select an image
* Press "get tags"
* Select the tags you want from a list of suggestions
* Press "Attach .. Tags" to add the selected tags to your image

calculates the start positon in the tag array based on the current page
and takes N tags from that array to show these in darktable
e.g. page 1 goes from 1 to 10, page 2 from 11 to 20 a.s.o.
the paginaton approach is related to a problem with the dynamic addition
of mutliple widgets https://github.com/darktable-org/darktable/issues/4934#event-3318100463
