implement transaction `call`

[krisbitney]

based on https://docs.ethers.org/v5/api/providers/provider/#Provider-call

This allows users to get the return value from a transaction, rather than just a transaction hash

Isn't that what callContractStatic is used for? https://github.com/polywrap/ethereum/blob/36e6f3331264732e73f3e236004416e82930ed64/wrapper/src/schema.graphql#L143-L149

Yes, but call has a different signature:

provider.call(tx)

Ah okay, so if I'm understanding correctly, the method you're looking to add to the ethereum wrapper would be something like:

callStatic(
  tx: TxRequest!
  connection: Connection
): StaticTxResponse!

?

[krisbitney]

Yes, exactly
