WIP: plug-ins: high bit depth support for HEIF format export.
So turns out that HEIF can support up to 16-bit per pixel since libheif 1.4.0.
Please don't push this because it actually doesn't work. The plug-in crashes when I try to export a more-than 8-bit image. I am only opening this because I am going to ask some help from libheif developers, as I am not sure if I am doing something wrong or if there is a bug in libheif.
