BDIP16 (Formal vote): Mandate Devs to explore migration of BSD to enable updates in rewards

This is similar to the current proposal under consideration by https://mith.cash/

We would mandate the devs to explore migration of BSD tokens (issue new sets of tokens, exchange with current) to enable updates in rewards. This will allow Basis Dollar to set up a Curve Metapool which uses a stableswap algorithm that makes it more efficient when conducting trades closer to the $1 peg.
