Hi,

Apparently ExDoc does not support (yet) debug_info keys, like used (at least with Erlang) when a module is compiled with: {debug_info_key,KeyString}?

For example, a foo module compiled with such a key, once given to ExDoc, results in:
warning: skipping docs for module :foo, reason: :no_debug_info

(moreover no mention of debug_info keys found with ex_doc -h|grep -i debug, in https://hexdocs.pm/ex_doc/search.html?q=debug_info or in https://github.com/elixir-lang/ex_doc)
