Step test case with public inputs (#23)

Browse Source 
* added step test case

* export solidity code

* just set proof's public input as public variables

* make serialization a command line option

* added flag to output solidity

* some changes to the benchmark file

* used gnark cherry picked bug fix

* removed fuzz testing

* added some logging

* more debug messages and test cases for the hint issue

* removed usage of goldilocks reduce

* removed prints

* removed GoldilocksReduce

* removed prints

* added a todo

* some serialization changes
