add imagemagick package (#424)

* add imagemagick package

* update xmake.lua

* update xmake.lua to default to using pic

* add bzip2 and libxml2 deps

* add lzma dep, disable djvu, jbig, and openmp

* add freetype and fontconfig deps

* create config options for deps, add each dep as needed

* remove some deps that couldn't be disabled, move more deps into some config options, disable deps that aren't installed

* add fix for threading, fix with -> without, set some sensible default config options (major used image formats)

* disable threading by default, but if it's enabled add the pthread syslink

* disable lcms, make configs entry look better

* add raw config option, disabe hdri

* replace libjpeg-turbo with libjpeg

* update link order

* I think I added the includedirs wrong

* nope I broke it so reverting

* rearrange link order
