Increase iUSD MCR to 120%

Because of Indigo’s and Cardano’s efficiency, iUSD was able to launch with a MCR of 110%. This helped bootstrap liquidity by minimizing the borrowing cost. Now that iUSD liquidity has been bootstrapped and the Stability Pool saturation is roughly 96%, we should increase the iUSD MCR to 120%. This in effect increases the borrowing cost which will help reduce the price spread of iUSD in the DEXs.
