Fix HA autodiscovery and add total entities

[antibill51]

Fix HA autodiscovery.

Add items from "total" topic into HA autodiscovery.

Optimizations are probably needed.

please check with latest version 0.5.78 it should include total values. Thank you for your fix attempt.

DynamicJsonDocument doc(128) to 256 (else mf=nul)
Fix unit problem for totals.
Fix topic problem for totals (else same as ch0)

Why not create a DTU entity grouping the totals, rather than repeating them for each inverter?

[lumapu]

I think it was too late for me, thank you for your review! It makes no sense to publish the totals more than once.

@lumapu
bd8de5f publish totals only once :)

[antibill51]

Now, Yieldday and Yieldtotal from the total topic have no exp_after flag in autodiscovery.
Waiting for midnight to see if Yieldday reset work.

@lumapu

@antibill51 maybe you take a look at the fix for #635 i think such a chunked request would solve the HA auto discovery problem too. Thanks!

@stefan123t I am interested in this kind of project to deepen my basics in code development. To be honest, I just discovered the term "prometheus metrics"... I'm not sure of the result, but I'll try to move on it as soon as possible. It's not easy to understand the whole of a project like yours, I took a while to make the previous few changes, but I'm someone who doesn't like to use a v0.5.41 when v0.5.7x exists ;)
