An Ethereum statemanager implementation

import { Account } from '@ethereumjs/util';
import type { AccountFields, Common, StateManagerInterface } from '@ethereumjs/common';
import type { Address, PrefixedHexString } from '@ethereumjs/util';
import type { SimpleStateManagerOpts } from './index.ts';
/**
 * Simple and dependency-free state manager for basic state access use cases
 * where a merkle-patricia or verkle tree backed state manager is too heavy-weight.
 *
 * This state manager comes with the basic state access logic for
 * accounts, storage and code (put* and get* methods) as well as a simple
 * implementation of checkpointing but lacks methods implementations of
 * state root related logic as well as some other non-core functions.
 *
 * Functionality provided is sufficient to be used for simple EVM use
 * cases and the state manager is used as default there.
 *
 * For a more full fledged and MPT-backed state manager implementation
 * have a look at the [`@ethereumjs/statemanager` package docs](https://github.com/ethereumjs/ethereumjs-monorepo/blob/master/packages/statemanager/docs/README.md).
