// Call Call invokes an arbitrary, network-specific procedure call with network-specific parameters.
// The guidance for what this endpoint should or could do is purposely left vague. In Ethereum, this
// could be used to invoke eth_call to implement an entire Rosetta API interface for some smart
// contract that is not parsed by the implementation creator (like a DEX). This endpoint could also
// be used to provide access to data that does not map to any Rosetta models instead of requiring an
// integrator to use some network-specific SDK and call some network-specific endpoint (like
// surfacing staking parameters). Call is NOT a replacement for implementing Rosetta API endpoints
// or mapping network-specific data to Rosetta models. Rather, it enables developers to build
// additional Rosetta API interfaces for things they care about without introducing complexity into
// a base-level Rosetta implementation. Simply put, imagine that the average integrator will use
// layered Rosetta API implementations that each surfaces unique data.
