Historical data availability needed for hardhat-chai-matchers

[cytadela8]

🌟 Feature Request

📝 Description

Hardhat chai matchers need access to historical balances and state. If possible we should implement eth_getBalance and eth_call for historical (non-latest) blocks.

🤔 Rationale

People use changeEtherBalance and chnageTokenBalance hardhat-chai-matchers. We claim right now that hardhat-chai-matchers just work, but this is not the case

📋 Additional Context

This is the essence of implementation of .changedEtherBalance in hardhat-chai-matchers:

  const balanceAfterHex = await provider.send("eth_getBalance", [
    address,
    `0x${txBlockNumber.toString(16)}`,
  ]);

  const balanceBeforeHex = await provider.send("eth_getBalance", [
    address,
    `0x${(txBlockNumber - 1).toString(16)}`,
  ]);
