Cannot bypass MM

[PatrickAlphaC]

Describe the bug
When working with a browser that also has MM installed, when you click "connect" on a UI, MM will popup, and there is no way for Rivet to be used instead

To Reproduce
Steps to reproduce the behavior:

1. Go to any app/site like aave, and hit connect wallet
2. Metamask will connect

Expected behavior
There to be a way for Rivet to connect instead

The UI would need to support EIP-6963 – this way it would be able to grab the EIP-1193 provider object associated with Rivet's unique rdns value (et.riv), instead of window.ethereum which Rivet and MetaMask are in a race condition to define.
