feat: Adds support for Vesternet Zigbee Sensors

[martyn-vesternet]

VES-ZB-DOR-025 Door and window sensor, exposes contact, tamper, battery and link quality
VES-ZB-PIR-021 Motion sensor, exposes occupancy, tamper, battery and link quality
VES-ZB-TEM-027 Temperature and humidity sensor, exposes temperature, humidity, battery and link quality

I refactored the code a bit, can you check if all is ok?

[martyn-vesternet]

Those changes seem to impact the reporting I'm configuring for each device though?

I try to set configuration so that it's a compromise on functionality / battery life and so that it matches that which I set on other platforms (Hubitat, SmartThings & Homey) for the Vesternet devices.

I prefer these for the humidity / temperature sensors:

min: 60, max: 1800, change: 100 ( 1 degree / percent change, every 60 seconds at most, every 30 minutes at least )

whereas the config from "modernExtend" seems to be:

min: '10_SECONDS', max: '1_HOUR', change: 100

IMHO 10 seconds is too frequent, it will generate many reports in environments where the temperature / humidity changes rapidly.

And for battery:

min: 600, max: 21600, change: 2 ( 1 percent change, every 10 minutes at most, every 6 hours at least )

(I just noticed I didn't set those correctly in my commit, so I will update them)

whereas the config from "modernExtend" seems to be:

min: '1_HOUR', max: 'MAX', change: 10

Which seems to only report on a 5 percent change and only report every 18 hours if no change?

Agree about these ones, please update the defaults.

Which seems to only report on a 5 percent change and only report every 18 hours if no change?

Yes, because it's unlikely that a sensors consumes more than 5 percent of battery every 18 hours
