Feature: Debug statement control

[pi0neerpat]

I'd like to propose two things:

1. Allow silencing console.logs
2. If desired, allow more logs

One solution to this is adding another option here:

https://github.com/superfluid-finance/superfluid-protocol-preview/blob/8ae78d1222066bbfce0f5b8a850f4eb3a24c2ff4/ethereum-contracts/js-sdk/Framework.js#L10

And be used like this:

    const sf = new SuperfluidSDK.Framework({
      // ...
      debug: "off" // available: ["off", "on", "verbose"] default: "on"
    })
