better document what the optional deps do

currently the README only mentions what deps are optional but has no
info on what they do. we had an issue where a user was confused about
what libexif is used for : https://github.com/nsxiv/nsxiv/issues/58

this makes it clear what each of the optional deps do so that users can
make more informed decision on weather they want something or not.
