mediainfo_alt WDX - Image version

[advice2020]

If the decision is ever made to add the following plugin into the official plugin bundle available on this site.
#47
I am suggesting to also offer a version that works for generating Image/Picture data as well.

It was mentioned that this plugin is based on the existing mediainfo WDX plugins available on other DC 3rd party plugin site.
Those mediainfo plugins also contain a version for Images/Pictures data
mediainfo-imagesize.lua
