feat: added IOU token #23

Closed hexonaut closed 3 years ago

Token implementation is flexible. It just needs to provide mint() and burn() functions. I've used a DSToken as an example, but we could also consider modifying DSToken to give a permanent approval to gov.

Few comments:

I've made govToken immutable, that should be merged in this branch and iouToken should also be immutable.
Maybe we can add a check in some test checking the balance of the iou token after lock and free.
