Values of 33-64 don't work with verilator #168

Also needs import platform again

Can you provide the verilator version you're using and an example test bench that shows the issue

https://github.com/StanfordAHA/lake -> run pytest tests/test_aggregator.py::test_aggregator[8-64], Verilator 4.018 2019-08-29 rev UNKNOWN_REV

Tests work when values not between [33-64] and they all work when I set max_bits=64 in verilator_target.py
