Helperify FFUF / Massdns

[TheTechromancer]

It would be nice to expose these brute-force functionalities as helpers. A module could request the helper by setting deps_helpers, and we would have a new directory of these helpers which each have an ansible playbook attached that will install the necessary binaries, i.e. ffuf or massdns.

httpx is another candidate for this, as it would significantly speed up our bucket enumeration and potentially other modules like ntlm.

EDIT: It would also allow any module to raise HTTP_RESPONSE, which would be pretty cool.
