* Updates nonce generation to adhere to fifo channel buffer before request executes by routine

* removed unused variables, lns etc

* Fix requested changes and added in timer that disengages lock if out of scope error occurs

* Fixed woopsy daisy issue

* Add benchmark, reduce time in force to unlock before stack insertion, add nil check for edge case

* Remove unusued waitgroup field

* use return nonce.Value and method, rm redundant nonce code, fix tests.
