Added Mainnet Beacons

We are excited to announce that Nodary beacons are now active on 13 mainnets. All data feeds that exist on testnets are also available on mainnets with the exact same usage.

The way the sponsor wallets are derived is changed to provide users more control over beacons and many more upcoming features. Due to this change, all sponsor wallet and beacon ids are changed. This is a one-time-only breaking change. Previously deployed beacon ids will be active until March 1, 2023.
