6fe243abbd ImageSize: make imageSize return an Either, not a Maybe. 
This will give us better error reporting options.
This is part of a fix for #1834.

5cb53a48d5 ImageSize: ignore unknown exif header tag rather than crashing. 
Some images seem to have tag type of 256, which was causing
a runtime error.

5c8c380a79 Better exif parsing, including image resolution. 
This introduces a dependency on binary >= 0.6, but we depend
on binary >= 0.5 via zip-archive anyway.

Closes #976.

3bf8012bf6 Text.Pandoc.ImageSize: Parse EXIF format JPGs. 
Note:  For now we just assign them all 72 dpi.  It wasn't
clear to me how to extract the resolution information.
At least the aspect ratio will be right, and 72 dpi is
the most common setting.

Closes #976.
