Adds ability to log raw websockets for debugging.

[thewhaleking]

Works something like this:

from async_substrate_interface import SubstrateInterface
from async_substrate_interface.substrate_addons import RetrySyncSubstrate
from async_substrate_interface.errors import StateDiscardedError
import logging

logger = logging.getLogger("raw_websocket")
logger.setLevel(logging.DEBUG)
log_handler = logging.StreamHandler()
logger.addHandler(log_handler)


def main():
    with SubstrateInterface("wss://lite.sub.latent.to:443", _log_raw_websockets=True) as substrate:
        current_block = substrate.get_block_number()
        old_block = current_block - 1000
        try:
            substrate.get_block(block_number=old_block)
        except StateDiscardedError:
            pass
    with RetrySyncSubstrate(
            "wss://lite.sub.latent.to:443", archive_nodes=["ws://178.156.172.75:9944"], _log_raw_websockets=True
    ) as substrate:
        assert isinstance((substrate.get_block(block_number=old_block)), dict)


main()
