getRegisters() always adds 25ms delay

[SushiRemover]

i noticed that any getXXXFromRegister call takes ~31ms, so i dug deeper and found that in getRegisters() it adds a Delay of 25ms presumably for when the message fails and then wants to retry (correct me if im wrong).

Long story short: i changed

while (respSize != (numRegisters*2 + 5) && tries < 10)
    {
        // Send out the command (this adds the CRC)
        respSize = sendCommand(command, 8);
        tries++;

        delay(25);
    }

to

while (respSize != (numRegisters*2 + 5) && tries < 10)
    {
        // Send out the command (this adds the CRC)
        respSize = sendCommand(command, 8);
        tries++;

        if(respSize != (numRegisters*2 + 5)) {
            delay(25);
        }
    }

So it only adds the Delay if the response size is wrong, works for me, and now i have times of ~7ms per call.

You could argue that modbus needs these delays, but as for now i dont see anything where its needed, and the sendCommand() actively waits for a response with a delay of 1ms until it gets an answer anyways, so i see this as a worthy performance improvement.
