imagemagick-full is needed on MacOS

[sorokine]

On MacOS with iterm2 using imagemagick from brew causes the following error attempting to render an image:

.nvim/lazy/image.nvim/lua/image/processors/magick_cli.lua:76: magick: unable to read font `' @ error/annotate.c/RenderFreetype/1660.
...

Using imagemagick-full instead of imagemagick fixes the problem. However, do not install imagemagick-full if imagemagick is already installed, uninstall imagemagick first:

brew uninstall imagemagick imagemagick-full --ignore-dependencies
brew install imagemagick-full
