new package: pillow-heif

[wszqkzqk]

• For the heif feature of ocrmypdf

[striezel]

Note that there are two HEIF packages for Python from the same author with slightly different naming: pillow-heif and pi-heif. They come from the same repository (see here and there), but they are using different namespaces.

This is a light version of Pillow-Heif with more permissive license for binary wheels.

It includes only HEIF decoder and does not support save operations.

All codebase are the same, refer to pillow-heif docs.

The only difference is the name of the imported project.

As far as I can see, ocrmypdf uses pi-heif and not pillow-heif. So packaging one while ocrmypdf seems to need the other one is probably not a good idea.
