todo

• i need to break out those code changes into it's own golang module so that we don't break the other honeybadger TCP injector tools. (I'll be doing that in another dev branch as usual)

my latest here -> https://github.com/david415/HoneyBadger/tree/93.add_inference_attack.1

all the tests should pass in this branch. i've broken out the inference injector api into it's own module.
