ISO8583 LengthPrefixedBinaryTCPClientImpl does not support standard message

### Expected behavior

Given a ISO8583 ASCII standard health check message: `00670800822000000800000004000000000000000409111530088001909916088001081`

And
Setting up TCP Sampler to use: `LengthPrefixedBinaryTCPClientImpl` with config: `tcp.binarylength.prefix.length = 4`

Then: TCP Sampler should be able to determine whether the message is ready or no.

### Actual behavior

For Response: `00690810822000000A0000000400000000000000040911153008800190991608800100081`

### Steps to reproduce the problem

1 - Clone this project: https://github.com/gdiazs/demo-iso8583
It is a server socket on top netty. Just run the main: **com.example.Main.**

2- Then in same repo there is a JMX script file : **ISO Performance.jmx** import to JMeter.
Make sure port 5000 is not being used by another process.

3 - Open JMeter's Log viewer and run script

4 - log messages shows up, request and response does not work.

NOTE:
Work around
- Happy Path:

On TCP sampler remove LengthPrefixedBinaryTCPClientImpl, then TCP implementation by default is setup, configure read timeout 1000 or 3000, then success output is faced.
