Consolidate step count between loda-cpp and loda-rust

[ckrause]

We should ensure that loda-cpp and loda-rust produce the same step counts. Currently they are different:

PROMPT> loda eval A41 -t 20 -s
79,205,389,629,939,1328,1799,2330,2923,3607,4397,5270,6261,7355,8540,9789,11180,12654,14282,16005
PROMPT> loda-rust eval 41 -t 20 --steps
70,179,337,542,806,1136,1535,1984,2485,3062,3728,4463,5297,6217,7213,8262,9430,10667,12033,13478
