[SenecHome] Add writeable Charging Modes

[BigFood2307]

This PR improves the SenecHome Binding by adding access to two writable charging modes for the battery systems.
This means adding the general capability of write commands to the binding and implementing the HTTPS commands for the necessary parameters.
It was shortly discussed in the Bindings Forum thread
With this addition the user can now force the battery system to charge to full or enter it into storage/transport mode.

Only one other person was able to test the new version. They had issues, although that might have been due to missmatched openHab versions.
On my own system, the updated binding has been running for ~6 months without issue.
Here is the binary I have been using for oh 4.2

👍
Looks good to me, also compared to the info I could reverse engineer from my senecs web interface. I can't test it, because my senec is one them which are not working and I still waiting for replacement since about a year.

How do these two charging modes relate? From the descriptions they seem conflicting, If you turn on both switches, what will happen?

Did you consider to have one chargeMode channel, that contains a list of possible options like: lithium charge, safe charge, nomale charge mode etc. ?

True, they are conflicting. I think I tested it some time ago and turning a second mode on, it would turn the first one back off.
I can test that again on the weekend.

A single channel with 3 options never entered my mind, but could actually be a good idea. I will look into how I can implement fixed state options for the channel.
