Adding support for "Develco AMS HAN sensor (EMIZB-132)"

So I’ve been going at it for a while now and I’m at a loss on what to do next. Posting what I have so far in the hopes that someone can help me out a bit.

This is a device that connects to the HAN-port on a digital electricity meter and it should be able to read electrical measurements from the device.

Here is the datasheet for the device. https://www.develcoproducts.com/media/1783/emizb-132-technical-manual-emi-norwegian-han.pdf

This is the initial log when I connect the device in HA: https://gist.github.com/SilentFez/94cdc5a6aa953d648323b403a6247dcc

And this is the log after adding the following in devices.js

{
    zigbeeModel: ['EMIZB-132'], 
    model: 'emizb-132',
    vendor: 'Develco',
    description: 'Wattle AMS HAN power-meter sensor',
    supports: 'Monitoring stats from central household power-meter',
    fromZigbee: [],
    toZigbee: [],
},

https://gist.github.com/SilentFez/8e28969c0a677a22c46cad9d7baa9afd

And this is the log for when I add the converter that is showing up in the second log: https://gist.github.com/SilentFez/026af1cf913fd899d1430f9c756f8b63

When I add the device in homeassistant.js and try to pair it, nothing seems not show up and I cant seem to get any other readings for converters in the logs.

Update 2: I contacted Wattle and asked them if it was possible to get the new firmware for the device. But I need to have their bridge/gateway in order to update it myself. But they were nice enough to offer to update it for me, so if I send the device to them they will make sure to upgrade it to the 2019 version that is needed for the Aidon meters. So if anyone else were to bump in to the same problem they could try and do the same, just ask if they are willing to update it for you.

@SilentFez thanks, will push it to the dev branch soon.
