base: add ADEiger module.

This module uses libzmq to interact with the detector data stream.

Since Pilatus4 support hasn't been released yet and we are interested in
using it, we are using the latest commit from the master branch instead
of a tagged release. Unfortunately, this commit also adds an unwanted
dependency on lz4 for the tests scripts, that are being removed in an
unmerged PR [1]. Add a patch to remove this dependency.
