After upgrade failed to install node-red-contrib-mcp23017chip

Quick update.
Yeah, downloading mcp23017chip, changing "i2c-bus": "~1.2.2" to "i2c-bus": "~5.2.1" and installing it locally via npm i /path/to/mcp23017chip did the thing. All is working good now

Also, I'll check the Python script pushing updates to MQTT way. No polling sounds more sense here.

Thanks
