An Ethereum statemanager implementation

/**
 * 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 `@synthesizer-libs/statemanager` package.
