FreeImage on ARM Mac requires -DPNG_ARM_NEON_OPT=0

[Dan Foster]

During linking, the following error comes up:

Undefined symbols for architecture arm64:
  "_png_init_filter_functions_neon", referenced from:
      _png_read_filter_row in pngrutil.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libfreeimage.3.18.0.dylib] Error 1

This seems to be coming from the version of LibPNG bundled with FreeImage but I am not too sure. I will keep digging.
