Cherry-picking new status page from @selbstmacher #82

Also fixes a scaling bug for energy data in SMA parser.

@oldboys92 please test before I merge

@TheRealMoeder tested successfully. LGTM. Here my summary:

• I personally prefer having the unit after after the label instead of having it after the value (like this Voltage (V): 230.0), but it's really not a big issue
• I think the unit for Energy Data (power) is easier to read in kWh (ex 2435.3 kWh instead of 2435343.2 Wh)🔍
• The main page feels a little bit unfriendly to read on my big screen, I need to scroll down to read all information (even in 100%, I usually have 120%). Instead of additional rows for totals an additional column might solve it. On a phone, one needs to scroll anyway, since the columns are rendered differently.
• Everything else works here, including the blinking of the blue led💡

Thanks for your feedback. I modified the status to have 4 columns with dynamic scaling, changed units to kWh and also fix a long-time bug I never noticed.
