fix: add new Ethereum types namespace to fix types

[davidmurdoch]

We fixed our Ethereum RPC types and put them in a new namespace: Ethereum! Use it as follows:

import Ganache, {ProviderOptions, Ethereum} from "ganache";

async function getLatestBlock(): Promise<Ethereum.Block> {
  return await provider.request({method: "eth_getBlockByNumber", params: ["latest"]});
}
async function getAccounts(): Promise<string[]> {
  return await provider.request({method: "eth_accounts", params: []});
}
async function sendTransaction(transaction: Ethereum.Transaction): Promise<string> {
  return await provider.request({method: "eth_sendTransaction", params: [transaction]});
}

const options: ProviderOptions = {
  fork: { network: "mainnet" }
};
const provider = Ganache.provider(options);
const accounts  = await getAccounts();
const block = await getLatestBlock();
console.log(block.number); // string
const transaction: Ethereum.Transaction = { from: accounts[0], to: accounts[2], value: "0xffff" };
const hash = await sendTransaction(transaction);
console.log(hash); // string

If you find issues or can think of ways we can further improve our types please open a New Issue (you can view all existing type issues by filtering our issues by the typescript label).

I won't pretend to understand those types tests, but they sure do look cool!

This was an initial pass through, I still haven't tested any of it.

I'm having second thoughts about this name, SignedTransaction. That name made me think it was equivalent to a raw transaction, like what eth_signTransaction returns. :/

Excited to have this one merged! I've got some tiny clean up requests
