Fix all the nasty stuff

Fixed Incomplete Data Reads in Simulator and Node

Simulator (listen method)

• Updated the data reading logic to ensure that all expected bytes are read from the socket before processing.
• Implemented a loop to accumulate incoming data until the total received bytes match the expected message length.

Node

• Adjusted the data reading mechanism when communicating with the simulator to read all expected data.
• Added a loop to continuously read data until the expected length is met, ensuring complete data reception before processing.

Adjusted JSON Parsing in Simulator:

• Modified the simulator to parse JSON directly from bytes without first decoding to a string.
• Ensured compatibility and correct parsing of the payload by handling bytes directly.

Improved Handling of Incomplete Messages in read_messages Function

• Updated the read_messages function to handle incomplete data reads gracefully.
• Instead of treating incomplete messages as errors, the function now waits for more data to arrive, improving reliability during normal operation.

Modified _handler Method in ABCIServer

• Adjusted the buffer management in the _handler method to correctly handle incoming data.
• Removed processed data from the buffer after each iteration to prevent buffer overflow.
• Ensured that incomplete messages are handled without logging errors, enhancing performance and stability.

Removed Unnecessary Error Logging:

• Eliminated error messages that were being logged due to incomplete data reads, which are expected in socket communication.
• Improved log clarity by only logging actual errors, reducing noise and aiding in troubleshooting.

Type of change

• Bug fix (non-breaking change which fixes an issue)
