v1.16.1 - fix building gdk-pixbuf loader Latest

Small maintenance update that fixes building the gdk-pixbuf loader.
The source package name has also been changed back to the old naming scheme.

v1.16.0 - Regions / chroma quality / uncompressed codec

This is a large release with many new features.

    Support for HEIFv2 regions (rgan) and user annotations (udes). This enables \ 
to annotate regions in the image with several geometric primitives and assign \ 
user text descriptions to them. Thank you @bradh for the contributions. Mask \ 
support will be added soon.
    Previously, chroma was downsampled and upsampled with a simple \ 
nearest-neighbor method. We now included the sharp-yuv chroma downsampling \ 
algorithm. This gives improved image quality when images are downsampled to \ 
4:2:0 and upsampled with bilinear interpolation. Thank you @maryla-uc for the \ 
contributions.
    The bilinear chroma upsampling and averaging downsampling algorithms are \ 
also new. You can choose what to use.
    We added experimental support for decoding uncompressed images according to \ 
ISO/IEC 23001-17:2023. This is work in progress and currently decoding only. \ 
Thank you @bradh for the contributions.
    There are new APIs to query the image transformations. Thus, you may choose \ 
to get the original image and apply the transformations yourself.
    A longstanding bug writing non-compliant 'ispe' boxes (image size) has been \ 
fixed. Files should be standard compliant now.
    When building binary packages, you can now make use of a CMake presets to \ 
set a default configuration.
    The deprecated autotools build files have been removed.
