Proposal #2, Change the current expansion rate

So far we've seen the protocol working as expected, going under peg getting back over peg, and having a couple of “peg epochs”, epochs where no TOMB or TBOND was emitted because the price was between 1-1.01 (less than 1% away from the target price).

However, in order to keep the protocol working as expected and to keep it stable, we would like to to propose a (temporary) reduction on the current expansion rate, in order to slow down our emissions until our new use cases get released. The reason being, right now we feel like the buying pressure and the burning mechanism in place cant keep up with the emissions. Once we've got our new use cases up and running to increase the burning of tomb, we will have the possibility to vote on the expansion rate once again.

We've come up with the following 3 options:

1. Keep the expansion rate at its current level of 1.5% (emissions outpacing burning mechanism as of right now)
2. Reduce the expansion rate to 1.25% (rewards will be cut by 17-20% on the masonry so APR will go down from 1200 to 960 for example)
3. Reduce it to 1% (rewards will be cut by 34-40% on the masonry so APR will go down from 1200 to 720)

We understand that lowering the APR of the Masonry for the short term might feel like a bit of a slap in the face for some of us as we've gotten accustomed to it but it could benefit the project in the long run.
