SIP #000: Launch June cUSDC market

With reference to the SIP discussed here: https://gov.swivel.finance/t/sip-000-launch-june-cusdc-market/15

I'd like to propose the addition of a June 2022 cUSDC market. We currently have one live maturity, March 2022, and with current liquidity can begin considering launching additional lending markets.

The primary motivation here is to begin to offer a bit of a yield curve without diluting liquidity.

Further, this June 23rd USDC maturity also aligns with Yield Protocol’s june maturity. This allows for additional contextual lending and aggregation and potential arbitrage between the two over time.

These maturities also align with FTX’s quarterly futures maturities which provides additional contextual information when compared to potential USDC or other funding yields.
