Deye/Sunsynk 3-phae inverter sensors for inverter and load added

[proggaras]

Some sensors for the Deye/Sunsynk 3-phae inverter where corrected and added.

• Inverter L1-L3 voltage
• Load frequency

Thx. for reviewing.

    Sensor(630, "Inverter L1 current", AMPS, 0.01),
    Sensor(631, "Inverter L2 current", AMPS, 0.01),
    Sensor(632, "Inverter L3 current", AMPS, 0.01),

According to modbus docs, the above need to be signed like so:

    Sensor(630, "Inverter L1 current", AMPS, -0.01),
    Sensor(631, "Inverter L2 current", AMPS, -0.01),
    Sensor(632, "Inverter L3 current", AMPS, -0.01),

Actually I used this doc: https://forum.iobroker.net/assets/uploads/files/1712644425833-c3ca14a0-178c-4f68-be8c-fa68a414b97b-deye-sun-inverter-modbus-en.pdf
How do you decide if there is a "-" or not?

In the third column you can see it says S16 - signed 16 bits. For signed registers, the code handles them as such when factor is below 0.

That makes 100% sense for current. I already pushed a new commit.

Thanks @proggaras!
