[bug] Incorrect filter method names

[eshaan7]

The following 3 method names are incorrect:

As per the spec, these should be eth_newFilter, eth_newBlockFilter and eth_newPendingTransactionFilter respectively:

Also, these 3 methods seem to be missing corresponding Wasm bindings. Is that intended?

Ah good catch. We should change this and make sure the names in the Client/Node objects are also made to align with the jsonrpc names for consistency. And yes lets add these methods to the wasm binding as well.

Raised PR #450 removing the incorrect get prefix from these 3 methods. This is technically a breaking change btw.

Will be raising a separate PR for the Wasm bindings because that is missing for few other methods beyond these 3. Tracking in #451.
