Update request.go to fix concurrency nonce issues (#285)

Browse Source 
* 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.

* Fix linter issue: unnecessary conversion
