feat: add methods to modify account (#2337)

This PR adds the evm_setAccountBalance, evm_setAccountCode, and evm_setAccountStorageAt RPC methods. Just as their names suggest, these methods let you set the balance, code, and storage (at a specified slot) for an account.

evm_setAccountBalance:

const balance = "0x3e8";
const [address] = await provider.request({ method: "eth_accounts", params: [] });
const result = await provider.send("evm_setAccountBalance", [address, balance] );
console.log(result);

evm_setAccountCode:

const data = "0xbaddad42";
const [address] = await provider.request({ method: "eth_accounts", params: [] });
const result = await provider.send("evm_setAccountCode", [address, data] );
console.log(result);

evm_setAccountStorageAt:

const slot = "0x0000000000000000000000000000000000000000000000000000000000000005";
const data = "0xbaddad42";
const [address] = await provider.request({ method: "eth_accounts", params: [] });
const result = await provider.send("evm_setAccountStorageAt", [address, slot, data] );
console.log(result);

fix: serialize eth_subscribe log data (#2331)

A previous PR (#2331) fixed how we emit logs on eth_subscribe for EIP-1193 "message" event types, but unintentionally broke those messages for the legacy "data" event types. For those of you still using the legacy event types (cough cough Truffle), this fix should get those events working again.

fix: allow hex string for coinbase option in cli (#2405)

The miner.coinbase option allows you to specify the address to which mining rewards will go as a either a string representing the hex-encoded address or a number representing the index of the account returned by eth_accounts. However, a hex address sent with this option was incorrectly interpreted as a (verrrrrry large) number, causing a startup error. This fix correctly parses the argument so that the option can be used as expected.
