NodeGRPCService class

A gRPC service client for interacting with a remote node.

This class provides methods to fetch transaction, block headers and bodies, current mempool, broadcast a transaction and synchronization traversal from a remote node using gRPC protocol. It requires a host and port to establish a connection with the remote node, and ChannelOptions can be optionally provided for further configuration
