Code and readme out of sync

[abhinavsinha001]

Tried to set this up and run - seems there are lot of refactoring and updates to code parameters which are not reflected in README.

e.g This command doesn’t work

go run examples/signer-server.go --frequency 5s --logtostderr --body '{"sample": "request"}' --origin_callsign=ssai-serving.tk --url='http://ads.ad-exchange.tk:8090/request?param1=example&param2=another' --send_requests

The path and params have changed to

go run examples/signer-server/signer-server.go -frequency 5s --body '{"sample": "request"}' -origin=ssai-serving.tk -url='http://ads.ad-exchange.tk:8090/request?param1=example&param2=another' -send_requests

I will try to fix as much of this as possible and raise a PR. I would request code contributors to please update the readme as well.

Additionally I see there is no working domain with that I can test with
ssai-serving.tk doesn’t work

No record found for _delivery._adscert.ssai.tk in 126.8093ms: lookup _delivery._adscert.ssai-serving.tk on 8.8.8.8:53: no such host

Neither does publica-ssai.com doesn’t work - seems there is private key mismatch

Can someone provide steps to get a bare minimum domain and key setup for validating this. Or am I missing something?
