Publish inverter ID via simple_mqtt

I was wondering why this didn't happen for simple_mqtt, but for Home Assistant it did. It makes sense when you want to push data from multiple identical inverters to a single MQTT server, so you can distinguish between them.

• [x] run cargo clippy and fix all issues
• [x] run cargo fmt to format all source files

i also have another version running where the inverter ID is part of the published topic and not the payload, which for my personal setup makes more sense. if that's something you'd prefer, i can open another PR and close this one.

I think it would make sense to have the inverter ID as part of the published topic. It would be a breaking change however for the existing users and their applications that depend on the previously used topic. Maybe we can add a parameter "use_sn_in_topic" or something like that to make it optional

@DennisOSRM already seems to have started to implement reading environment variables in #61 as it looks like. what's the status of this? the fix in this PR here should be done regardless i think, since the home assistant config already does that.

also there is #116 which requests that, basically. let me know if i should pick this up.

Oh yes, happy to consider PRs since I am somewhat spread thin with day job and other stuff right now. 👍🏽

I am of the same opinion. It makes sense to have the inverter id as part of the topic.

alright. closing this one then.
