Add (battery) discharge profile support for solaredge

[Gifford47]

Is your feature request related to a problem? Please describe.
I wouldn't like to use my house battery for the ev. Therefore i want to "control" the energy used by the ev. Currently i have no suitable solution to restrict my hems to use the house battery.

Describe the solution you'd like
A possibility to change the hems/battery profile (f.e.: maximize export mode, self consumption, off, ...). I dont know if evcc currently needs this feature, but you could also use it with my smarthome system. F.e.: if evcc has set a target soc and a target time, i could change the battery profile with my smarthome from self consumption to off while loading. I know that the house isn't supported by battery also, but that's the compromise i go with. In my case evcc starts loading in the morning, so that`s not a big deal.
I great option would be to change the battery profile by the evcc api (like all the other values/registers that are currently supported).

Describe alternatives you've considered
On googling i found some interesting topics on homeassistant community. For example:

Setting battery charge/discharge profile via HA integration
Add storedge control via HA integration

and here is the solaredge Technical Note – Power Control Protocol for
SolarEdge Inverters
on Page 17 you find the charge/discharge modes from 0-7
