e1a3751936 CMake: make use of qt_add_plugin for plugins 
Currently it will only produce shared library binaries as plugin.
This could make building static imageformats plugin much easier.

402dfb5de3 psd: Fix alpha blending 
PSD files are saved with as alpha premultiplied. The problem is that alpha refers to white instead of black so it requires transformation formulas. Then, to conver PS premultiplied to QImage premultiplied you have to use the following formula:

* V = Alpha + Vps - Max (C, M, Y, K, R, G, B, Gray, L\* components)
* V = Vps + (Alpha - Max + 1) / 2 (a\*, b\* components)

Where Max is the maximum value depending on the image depth and Vps is the valued read from the file.

05bd9397b3 raw: tweak seek implementation 
libraw uses fseek when doing files, which allows seeking past the end
without problems, so do the same, otherwise when we report oss-fuzz
issues they say "give me an example to reproduce" and since our seek
and their seek don't behave the same it's hard to convince them
to fix their code

a30f043e5d heif: rewrite plugin to use only libheif C API 
Using C-API instead of C++ libheif API has following advantages:
- More libheif features available (for ex.: strict decoding)
- Linking with static build of libheif is possible
- No need to enable exceptions

dcab3a06ab raw: LibRaw_QIODevice::read: fixed possible partial reading of an item 
- If the size of an item is greater than 1 byte, it must be ensured that it is not partially read.
- In many readings, LibRAW gives an error if a partial number of items are read so I always try to read everything.

460085 was fixed, so a workaround is added.

9ab64dbf22 heif: use heif_init/heif_deinit with libheif 1.13.0+ 
In recent libheif, application should use
heif_init/heif_deinit calls. Unfortunately, these calls are
not thread-safe in released 1.13.0 version yet (will be in the
future) and HEIFHandler is often created in different threads.
So we have to guard their use with a mutex.
