Fix compile-time issue involving implicit declaration of mapclut_paletee() (#1648)

Browse Source 
* Fix implicit declaration error on some systems.

This commit fixes a compile-time error regarding an implicit declaration
of mapclut_paletee() on some compilers and compiler versions.  Notably,
Arch Linux and Ubuntu 24.10 seem to be affected.

The error resolved is:

```
../src/lib_ccx/ocr.c: In function 'ocr_rect':
../src/lib_ccx/ocr.c:922:9: error: implicit declaration of function 'mapclut_paletee' [-Wimplicit-function-declaration]
  922 |         mapclut_paletee(palette, alpha, (uint32_t *)rect->data1, rect->nb_colors);
      |         ^~~~~~~~~~~~~~~
```

This was resolved by `#include`-ing "ccx_encoders_spupng.h" in the file
src/lib_ccx/ocr.c.  Thanks to GitHub user @steel-bucket for sharing the
fix in this issue's comments.
