`subscription.endingBlock` is the ending block number for the range we want to receive data in;
setting to 0 means there is no end/we will continue indefinitely.
`subscription.headerFilter` has two sub-options: `off` and `finalOnly`. Setting `off` to true tells the super-node to
not send any headers to the subscriber; setting `finalOnly` to true tells the super-node to send only canonical headers.
`subscription.headerFilter` has two sub-options: `off` and `uncles`. Setting `off` to true tells the super-node to
not send any headers to the subscriber; setting `uncles` to true tells the super-node to send uncles in addition to normal headers.
`subscription.trxFilter` has three sub-options: `off`, `src`, and `dst`. Setting `off` to true tells the super-node to
not send any transactions to the subscriber; `src` and `dst` are string arrays which can be filled with ETH addresses we want to filter transactions for,
