added b+g e-tech ds100 / ws100 meters

Fix #17105

Hi,

I added both meters mentioned in #17105

Test on my site looks okay:

WS100 (1phase):

mfriedr7@dev:~/github/ev_test$ ./evcc -c ~/evcc.yaml meter

test_ws100
------
Power:          178W
Energy:         171.5kWh
Current L1..L3: 1.27A 0A 0A
Voltage L1..L3: 229V 0V 0V
Power L1..L3:   178W 0W 0W

DS100 (3phase):

mfriedr7@dev:~/github/ev_test$ ./evcc -c ~/evcc.yaml meter
test_ds100
------
Power:          0W
Energy:         66.0kWh
Current L1..L3: 0A 0A 0A
Voltage L1..L3: 227V 226V 229V
Power L1..L3:   0W 0W 0W

(It is correct that it currently shows 0 watts. The meter is connected to the heating element of the heat pump, which is currently not active)

@premultiply I'm not happy with this pattern but also don't have a (much) better idea. Wdyt?

@Vogelbecker Did you implement all Registers? It looks like it has many...
(https://data.xn--stromzhler-v5a.eu/manuals/bg_ds100serie_de.pdf)
Maybe even a better Alternative to a SDM630 and cheaper (DS100-30B at 45€)

Hi,
as you can see above.
Currently there are the current voltages, currents and power for each phase
And also total power and active power.
What else do you need?

Well, as it is always interesting to see what a in my case heat pump is doing
in terms of power factor correction - I am always a fan of taking all you can get ;)
And from the looks of it it is more powerful than the SMD630...
