[Bug]: "Add support for user-defined extra sensors" seems to be out of date

[BradleyFord]

Describe the issue

I am struggling to replicate due to the large number of underlying code changes, if is possible to update this commit to be a better reflection of the current changes require?

@BradleyFord if its of assistance, have a look at this current pull request: #768
This was adding 5 sensors (and removing 2 that give incorrect readings). With the Library ( https://github.com/wlcrs/huawei-solar-lib ) already defining these modbus registers, it is a matter of adding them into the sensor.py, strings.json and language files. You do need to keep the sensors in the same order as the corresponding register for them is listed in the library.

I've removed the outdated branch and did a small update to the wiki. But mainly, as Roving-Ronin said: look at #768 to see how you can add extra sensors.
