Solana Geyser gRPC Multiplexing and Reconnect

This project provides multiplexing of multiple Yellowstone gRPC subscriptions based on Fastest Wins Strategy.

• Multiple Futures get merged where the first next block that arrives will be emitted.
• No guarantees are made about if the messages are continuous or not.
• Reconnects are handled transparently inside the Futures.

Disclaimer: The library is designed with the needs of LiteRPC in mind yet might be useful for other projects as well.

The implementation is based on Rust Futures.

• Should not be used with commitment level PROCESSED because slot numbers are not monotoic.
• Library needs messages to be in order and provide slot information to work properly.
