ReadTimeout will not be considered when using async

[endrelovas]

Hello,

With reference to:

FluentModbus/src/FluentModbus/Client/ModbusTcpClientAsync.cs

Line 54 in bbd7dcd

using var timeoutCts = new CancellationTokenSource(_networkStream.ReadTimeout);

timeoutCts will not be cancelled ever IMO. _networkStream.ReadTimeout is not considered when you call it Async.

Do I miss something here?
