Support PDF image preview in diff

Hello,
the possibility to preview the different versions of an image is incredibly useful (when writing a scientific paper for instance).
But for large very documents, it is advised to use PDF images.
Unfortunately the current version of gitkraken interpret PDF images as binary text files which prevent to visualize the different version.
I understand that it can lead to a problematic feature when large PDF files are used within gitkraken but I think adding the possibility to visualize them would be beneficial.
Thanks

Vincent
