Hello.
First of all, thank you for this awesome library.

I had originally used this library on a nano without issue, but needed some extra ram so decided to switch to the ATmega 1284 using MightyCore.
However, after about a week of trying to figure it out, i am am unable to get the 1284 and the NAOMI to communicate.

Setup:
Arduino IDE 1.8.10
Naomi
Custom 1284 PCB (Standard MightyCore pinout)
Pins D8 for JVS Data+, D10 for JVS Data- and D15 for JVS Sense
LED on D0.
I have also setup a board as a JVSMonitor.

The LED blinks 3 times during booting the NAOMI or switching to the test menu, and JVSMonitor pics up some communication which i have attached below.
1284boot.zip

I have tried both the current version of jvsio, and commit d070476 just in-case there was an issue with the current version, but there was no change.

When compiling either of those commits, Arduino IDE throws an error "'TCCR2' was not declared in this scope", so i changed the code in MightyClient.cpp / BaseClient.h to TCCR2A or TCCR2B and it compiles without issue, but results in the same non syncing / communication issue.

I'm not sure if I'm missing anything that is causing this issue, or if the MightyClient just doesn't work, but any help would be greatly appreciated.

Thank you for your time.

Now jvsio library does not have an interface to monitor downstream sense signal, but just assumed it as terminated.

To support multiple clients, jvsio library should provide a client interface to monitor downstream sense signal, and change address command handling so to follow the multi-client negotiation protocol, ignoring it until downstream client says ok.

Hi, I am the guy on twitter that proposed the implementation of the Mega 2560 PRO MINI (@itslemcy).
Like this, we can achieve a two player configuration support since there are so many gpio's!
Thanks a lot!
