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
